INTERRUPTS2_ENABLE_CNFG - Interrupt Control 2
INTERRUPTS3_ENABLE_CNFG - Interrupt Control 3
Address: 11H
Type: Read / Write
Default Value:00XXXXX0
Bit
Name
Description
7
T0_OPERATING_MODE
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when the T0 DPLL operating mode
switches, i.e., when the T0_OPERATING_MODE bit (b7, 0EH) is ‘1’.
0: Disabled. (default)
1: Enabled.
6
T0_MAIN_REF_FAILED
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when the T0 selected input clock
has failed; i.e., when the T0_MAIN_REF_FAILED bit (b6, 0EH) is ‘1’.
0: Disabled. (default)
1: Enabled.
5 - 1

Reserved.
0IN3_CMOS
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when the input clock validity
changes (from ‘valid’ to ‘invalid’ or from ‘invalid’ to ‘valid’), i.e., when the corresponding IN3_CMOS bit (b0, 0EH) is ‘1’.
0: Disabled. (default)
1: Enabled.
Address: 12H
Type: Read / Write
Default Value: 00X0XXXX

EX_SYNC_ALARM
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when an external sync alarm has
occurred, i.e., when the EX_SYNC_ALARM bit (b7, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
6T4_STS
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when the T4 DPLL locking status
changes (from ‘locked’ to ‘unlocked’ or from ‘unlocked’ to ‘locked’), i.e., when the T4_STS bit (b6, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
5-
Reserved.
4
INPUT_TO_T4
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when all the input clocks for T4 path
change to be unqualified, i.e., when the INPUT_TO_T4 bit (b4, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
