Configuration Flags

Operational Mode (CtrnConfig.OperationalMode_0 through

Ctr

nConfig.OperationalMode_2)

These bits apply to Counters 0 and 1 only.

This value determines how the A0 or A1 and B0 or B1 inputs are decoded when

assigned to counter 0 or counter 1.

TIP

The Ctr1Config.OperationalMode bits are reserved if the Number of

Counters equals 1. Attempting to set reserved bits will result in a

configuration error.

IMPORTANT

Do not change this value while the counter is enabled. Attempting to do

so will result in a BadModConfigUpdate error. See page 120 for a list of

prohibited settings.
