Bit 15 – TSYNCDIS Termination Synchronization Disable bit

ValueDescription
1

Termination of latched PCI occurs immediately
0

Termination of latched PCI occurs at PWM EOC

Bits 14:12 – TERM[2:0] Termination Event Selection bits

ValueDescription
111

Selects PCI Source #9
110

Selects PCI Source #8
101

Selects PCI Source #1 (PWM Generator output selected by the PWMPCI[2:0] bits)
100

PGxTRIGC trigger event
011

PGxTRIGB trigger event
010

PGxTRIGA trigger event
001

Auto-Terminate: Terminates when PCI source transitions from active to inactive
000

Manual Terminate: Terminates on a write of ‘1’ to the SWTERM bit location

Bit 11 – AQPS Acceptance Qualifier Polarity Select bit

ValueDescription
1

Inverted
0

Not inverted

Bits 10:8 – AQSS[2:0] Acceptance Qualifier Source Selection bits

ValueDescription
111

SWPCI control bit only (qualifier forced to ‘0’)
110

Selects PCI Source #9
101

Selects PCI Source #8
100

Selects PCI Source #1 (PWM Generator output selected by the PWMPCI[2:0] bits)
011

PWM Generator is triggered
010

LEB is active
001

Duty cycle is active (base PWM Generator signal)
000

No acceptance qualifier is used (qualifier forced to ‘1’)

Bit 7 – SWTERM PCI Software Termination bit

A write of ‘1’ to this location will produce a termination event. This bit location always reads as ‘0’.

Bit 6 – PSYNC PCI Synchronization Control bit

ValueDescription
1

PCI source is synchronized to PWM EOC
0

PCI source is not synchronized to PWM EOC

Bit 5 – PPS PCI Polarity Select bit

ValueDescription
1

Inverted
0

Not inverted

Bits 4:0 – PSS[4:0] PCI Source Selection bits
