 *
 * 2008-02-24 (Wilbert Pol):
 * - Added preliminary support for uPD7801
 *   For the uPD7801 only the basic instruction set was added. The current timer
 *   and serial i/o implementations are most likely incorrect.
 * - Added basic support for uPD78C05 and uPD78C06
 *   Documentation of the actual instruction set layout is missing, so we took
 *   the uPD7801 instruction set and only kept the instructions mentioned in
 *   the little documentation available on the uPD78c05A/06A. The serial i/o
 *   implementation has not been tested and is probably incorrect.

PA, PB, PC, PD, and PF is bidirectional I/O port
and PT is comparator input port in uPD7808.
uPD7807 uses PD port as data I/O and bottom address output,
and uses PF port as top address output.

NMI* is non maskable interrupt input signal (negative edge trigger).

INT1 is interrupt input (positive edge trigger). It can be used as
AC zero-cross input or trigger source of 16bit timer counter.

MODE0 and MODE1 is input terminal which decides total amount of
external memory of uPD7807 (4KByte, 16KBYte, and 64KByte).
It also decides number of PF ports used as top address output.
 4KByte mode: PF0~PF3=address output, PF4~PF7=data I/O port
16KByte mode: PF0~PF5=address output, PF6~PF7=data I/O port
64KByte mode: PF0~PF7=address output

RESET* is system rest terminal.

X1 and X2 does clock signal generation (connect OSC and condenser).

Vth is used to determine threshold voltage for PT port.
PT0~PT7 is connected to + input of each comparator,
and Vth deterimnes voltage connected to - input of PT0~PT7.
But the voltage of Vth is not directly connected to comapators.
It is connected via 16-level programmable voltage separate circuit.

HOLD and HLDA is terminal for DMA. RD*, WR*, and ALE is bus
interface signal (they are same type of Intel 8085).
Unlike 8085, I/O address space is not available, so IO /M* signal
does not exist. Read/write of external memory can be done
by RD*, WR*, and ALE only.

Vcc and Vss is main power source. Vdd is backup power source
for internal RWM (32 Byte).


PA and PB is I/O port. They have control register MA and MB.
If control register is set to 1, the port is input.
If control register is set to 0, the port is output.
They are set to 1 by reset.

PT is input-only port. It is consisted of input terminal PT0~PT7
and Vth (set threshold voltage). Each PT input has analog comparator
and latch, and + input of analog comparator is connected to
PT terminal. Every - input of analog comparator is connected
to devided voltage of Vth. Voltage dividing level can be set by
bottom 4bits of MT (mode T) register. The range is 1/16~16/16 of Vth.

Other internal I/Os are
8bit timer (x2): Upcounter. If the counter matches to specified value,
the timer is reset and counts again from 0.
You can also set it to generate interrupt, or invert output flip-flop
when the counter matches to specified value.
Furthermore, you can output that flip-flop output to PC4/TO output,
connect it to clock input of timer/event counter or watchdog timer.
Or you can use it as bitrate clock of serial interface.
Note: There is only 1 output flip-flop for 2 timers.
If you use it for timer output of 1 timer, another timer cannot be used
for other than interrupt generator.
Clock input for timer can be switched between internal clock (2 type)
or PC3/TI input. You can set 1 timer's match-output as another timer's
clock input, so that you can use them as 1 16bit timer.

16bit timer/event counter (x1): It can be used as
- Interval timer
- External event counter
- Frequency measurement
- Pulse width measurement
- Programmable rectangle wave output
- One pulse output
Related terminals are PC5/CI input, PC6/CO0 output, and PC7/CO1.
You can measure CI input's H duration, or you can output timing signal
(with phase difference) to CO0 and CO1.

serial I/F (x1): has 3 modes.
- Asynchronous mode
- Synchronous mode
- I/O interface mode
In all 3 modes, bitrate can be internal fixed clock, or timer output,
or external clock.
In asynchronous mode, you can
- switch 7bit/8bit data
- set parity ON/OFF and EVEN/ODD
- set 1/2 stop bit

For sr and sr1, all 6bits (S5, S4, S3, S2, S1, and S0) are used.
For sr2 and sr5, only 4bits (S3, S2, S1, AND S0) are used.
They are expressed as 'ssssss' and 's sss' in operation code.
Note that 's sss' (of sr2 and sr5) is located separately.
S0 is rightmost bit (LSB).
