STRP7~STRP0: STM CCRP 8-bit register, compared with the STM counter bit 15~bit 8
Comparator P Match Period =
0: 65536 STM clocks
1~255: (1~255) × 256 STM clocks
These eight bits are used to setup the value on the internal CCRP 8-bit register, which
are then compared with the internal counter’s highest eight bits. The result of this
comparison can be selected to clear the internal counter if the STCCLR bit is set to
zero. Setting the STCCLR bit to zero ensures that a compare match with the CCRP
values will reset the internal counter. As the CCRP bits are only compared with the
highest eight counter bits, the compare values exist in 256 clock cycle multiples.
Clearing all eight bits to zero is in effect allowing the counter to overflow at its
maximum value.
