PRSC1 and PRSC0 — PWM Prescaler Bits
Freescale Semiconductor
This buffered read/write bit selects which PWM value register is used if top/bottom correction is to be
achieved without current sensing.
This buffered read/write bit selects which PWM value register is used if top/bottom correction is to be
achieved without current sensing.
These buffered read/write bits allow the PWM clock frequency to be modified as shown in
1 = Use PWM value register 4.
0 = Use PWM value register 3.
1 = Use PWM value register 6.
0 = Use PWM value register 5.
When reading this bit, the value read is the buffer value (not necessarily the
value the output control block is currently using).
The IPOLx bits take effect at the beginning of the next load cycle,
regardless of the state of the load okay bit, LDOK.
When reading this bit, the value read is the buffer value (not necessarily the
value the output control block is currently using).
When reading this bit, the value read is the buffer value (not necessarily the
value the output control block is currently using).
When reading these bits, the value read is the buffer value (not necessarily
the value the PWM generator is currently using).
