14.12.19 PERBUFH – Timer/Counter Period Buffer register High
Bit 7:0 – PERBUF[15:8]: Period Buffer high byte
These bits hold the MSB of the 16-bit period buffer register.
14.12.20 CCxBUFL – Compare or Capture x Buffer register Low
The CCxBUFH and CCxBUFL register pair represents the 16-bit value, CCxBUF. These 16-bit registers serve as the
buffer for the associated compare or capture registers (CCx). Accessing any of these registers using the CPU or DMA
will affect the corresponding CCxBV status bit.
Bit 7:0 – CCxBUF[7:0]: Compare or Capture Buffer low byte
These bits hold the LSB of the 16-bit compare or capture buffer register.
14.12.21 CCxBUFH – Compare or Capture x Buffer register High
Bit 7:0 – CCxBUF[15:8]: Compare or Capture Buffer high Byte
These bits hold the MSB of the 16-bit compare or capture buffer register.
