INTERRUPTS3_ENABLE_CNFG - Interrupt Control 3
Address: 12H
Type: Read / Write
Default Value: 00X00000
Bit
Name
Description
7
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.
3AMI2_VIOL
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when IN2 has AMI violation, i.e., when the
AMI2_VIOL bit (b3, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
2
AMI2_LOS
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when IN2 has LOS error, i.e., when the
AMI2_LOS bit (b2, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
1AMI1_VIOL
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when IN1 has AMI violation, i.e., when the
AMI1_VIOL bit (b1, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
0
AMI1_LOS
This bit controls whether the interrupt is enabled to be reported on the INT_REQ pin when IN1 has LOS error, i.e., when the
AMI1_LOS bit (b0, 0FH) is ‘1’.
0: Disabled. (default)
1: Enabled.
