Table 43. PWM Low Byte Register (PWML)
Table 44. PWM Reload High Byte Register (PWMRH)
PWMH and PWML—PWM High and Low Bytes
These 2 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, shown in Table
44 and Table 45, store a 12-bit reload value, {PWMRH[3:0], PWMRL[7:0]}. The PWM
reload value is held in buffer registers. The PWM reload value written to the buffer regis-
ters is 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.
