External Reset
Input to the inverting oscillator amplifier
Output from the inverting oscillator amplifier
External ROM Access Enable (MiDAS2.0 family dose not use this pin.)
Address Latch Enable (If ALEOFF is set, active only for external RAM access)
This pin is also used for the parallel programming of FLASH memory.
Program Strobe Enable. Pull-up. Used for Special Input only.
(MiDAS2.0 does not support the code fetch from external ROM.)
I/O for MDS/ISP.
The pull-up resistor is always switched on. This port is quasi-bidirectional.
access external RAM or PCA1 drives output signals (C1EXn).
An 8-bit quasi-bidirectional open-drain I/O port. 5V Tolerant Input.
Note that the output is fully driven (push-pull) when P0 drives address/data to
