Standard I/O Port lines, generally used for keypad scanning or for LSB address
lines of coding table.
Port line 10 or emulation DXWR signal input.
Port line 11 or emulation DXRD signal input.
Port line 12 or emulation DXALE signal input.
Port line 13 or emulation EXDI signal input.

DP60 to DP67
Standard I/O Port lines, generally used for keypad scanning or for MSB address
lines of Coding Table.
Used for emulation purposes only. This output is the result of the OR operation
carried out internally on the RESET input and the Watchdog Timer reset and is
connected to the RESET pin of the 84C00.
Test pin T0 or external interrupt input.
Test pin T1 or timer/counter input (T1).
Active HIGH reset pin; normally connected to V
SS
as Power-on-reset serves the
same function.
