2.2 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 VTST

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 tRL for any other reset. After reset, the I/O, RAM,

ROM, Timer, SIOP and Interrupts are tested.
