The PWM high and low byte (PWMH and PWML) registers (see
contain the current 12-bit PWM count value. Reads from PWMH stores the value in
PWML to a temporary holding register. A read from PWML always returns this temporary
register value. It is not recommended to write to the PWM high and low byte registers
when the PWM is enabled. There are no temporary holding registers for Write operations,
so simultaneous 12-bit writes are not possible. When either the PWM high and low byte
registers are written during counting, the 8-bit written value is placed in the counter (High
or Low Byte) at the next clock edge. The counter continues counting from the new value.
PWMH and PWML—PWM High and Low Bytes
These two bytes, {PWMH[3:0], PWML[7:0]}, contain the current 12-bit PWM count
value.
The PWM reload high and low byte (PWMRH and PWMRL) registers (see
Table 67
PWM reload value is held in buffer registers. The PWM reload value written to the buffer
registers are not used by the PWM generator until the next PWM reload event occurs.
Reads from these registers always return the values from the buffer registers.
