The setting of the

IntActiveHigh register determines whether the wake-up occurs when the inter-

rupt goes high or low, assuming the interrupt has been enabled to cause a wake-up in the

IntL-

PEnable register.

Function

Int0ActiveHigh

Interrupt0 set to be active high or low

Interrupt0 goes low the ST20-GP6 wakes up from power down mode.

Interrupt0 goes high the ST20-GP6 wakes up from power down mode.

Int1ActiveHigh

Interrupt1 set to be active high or low

Interrupt1 goes low the ST20-GP6 wakes up from power down mode.

Interrupt1 goes high the ST20-GP6 wakes up from power down mode.
