AL Control event:
0: No AL Control Register change
1: AL Control Register has been written
2
(Bit is cleared by reading AL Control register
0x0120:0x0121 from PDI)
r/-
r/- 0

DC Latch event:
0: No change on DC Latch Inputs
1: At least one change on DC Latch Inputs
(Bit is cleared by reading DC Latch event
times from PDI, so that Latch 0/1 Status
0x09AE:0x09AF indicates no event. Available if
Latch Unit is PDI controlled)
r/-
r/- 0
2
State of DC SYNC0 (if register 0x0151.3=1):
(Bit is cleared by reading SYNC0 status
0x098E from PDI, use only in Acknowledge
mode)
r/-
r/- 0
3
State of DC SYNC1 (if register 0x0151.7=1):
(Bit is cleared by reading of SYNC1 status
0x098F from PDI, use only in Acknowledge
mode)
r/-
r/- 0
4
SyncManager activation register
(SyncManager register offset 0x6) changed:
0: No change in any SyncManager
1: At least one SyncManager changed
(Bit is cleared by reading SyncManager
Activation registers 0x0806 etc. from PDI)
r/-
r/- 0
5
EEPROM Emulation:
0: No command pending
1: EEPROM command pending
(Bit is cleared by acknowledging the command
in EEPROM command register 0x0502 from
PDI)
