Standard I/O port lines, generally used for keypad scanning or for LSB address byte of
code data.
Standard I/O port lines, generally used for keypad sensing, the wake-up function of
P14 to P17 can be removed by mask option.
Standard I/O port lines with 10 mA sink capability.
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.
Crystal or ceramic resonator or LC oscillator connections.
