Bit

Description

7-0

EVTENA (Event Enable). Bits 7-0 correspond to pins 7-0 of the speciﬁc Port. Each bit enables system

notiﬁcation by the corresponding GPIO pin. The bit has no effect on the corresponding Status bit in the GPEVST

0: Event Pending by corresponding GPIO pin masked

1: Event Pending by corresponding GPIO pin enabled

Bit

Description

7-0

EVTSTAT (Event Status). Bits 7-0 correspond to pins 7-0 of the speciﬁc Port. The setting of each bit is

independent of the Event Enable bit in the GPEVEN register. An active event sets the Status bit, which may be

cleared only by software writing 1 to the bit.

0: No active edge or level detected since last cleared

1: Active edge or level detected
