Description
PRI Interrupt Request
Indicates whether the PRI (RTC) interrupt request
is generated.
0: PRI interrupt request is not generated
1: PRI interrupt request is generated
ATI Interrupt Request
Indicates whether the ATI (RTC) interrupt request
is generated.

Description
Reserved
This bit always read as 0. The write value should
always be 0.
TUNI2 Interrupt Request
Indicates whether the TUNI2 (TMU) interrupt
request is generated.
0: TUNI2 interrupt request is not generated
1: TUNI2 interrupt request is generated
TUNI1Interrupt Request
Indicates whether the TUNI1 (TMU) interrupt
request is generated.
