power-on, an “ END” instruction should be entered in the group 32.

The interruption priority is shown as below while other trigger pins as well as JUMP (JP) command are

executing simultaneously during POI executing period:

POI > TG1F > TG1R > TG2F > TG2R > TG5F > TG5R > TG6F > TG6R > "JP" instruction.

Don’ t care

The MODE0.7 bit defines the output type of LED1 and LED2 pins as Flash output (3 Hz) or DC output.

The MODE0.6 bit defines the configuration of LED2/STPC pin’ s status as LED2 output or STPC

output. The MODE0.4 bit defines the trigger pin’ s debounce time as long debounce (50 mS) or short

debounce (400 uS). The MODE0.2 bit defines the behavior of the STPA/BUSY pin as STPA output in

normal mode or BUSY signal output in CPU mode. The bits 5, 3, 1 and 0 are don’ t care bits.
