SELF-CHECK MODE
The Self-Check program resides at mask ROM location $1E80 to $1FEF. This program
is designed to check the part’s functionality with a minimum of support hardware.
The Self-Check Mode is entered on the rising edge of RESET if the IRQ pin is at V
TST
volts and the TCAP pin is at logic one. RESET must be held low for 4064 cycles after
Power-on Reset (POR), or for a time t
RL
for any other reset. After reset, the I/O, RAM,
ROM, Timer, SIOP and Interrupts are tested.
