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.
