0 = No impact on TCM modules
1 = Enable both PCA counters simultaneously (override the EN_PCA Bits)
This bit is to start the two 16-bit counters in the PCA. For customers who
want 5 PWM, for example, this bit can start all of the PWM outputs.
0 = PCA counter is disabled
1 = PCA counter is enabled
EN_PCA Counter Run Control Bit. Set with software to turn the PCA
counter on. Must be cleared with software to turn the PCA counter off.
1 = Enable Counter Overflow Interrupt if overflow flag (OVF) is set
0 = PCA operates when CPU is in Idle Mode
1 = PCA stops running when CPU is in Idle Mode
Reserved
0 = Select 16-bit PWM
1 = Select 10-bit PWM
00 Select Prescaler clock as Counter clock
01 Select Timer 0 Overflow
10 Select External Clock pin (P4.3 for PCA0) (MAX clock rate = f
