• Bit 7:0 – PERBUF[7:0]
These bits hold the LSB of the 16-bit period buffer register.
14.12.19 PERBUFH – Timer/Counter Period Buffer H
• Bit 7:0 – PERBUF[15:8]
These bits hold the MSB of the 16-bit period buffer register.
14.12.20 CCxBUFL – Compare or Capture x Buffer register L
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]
These bits hold the LSB of the 16-bit compare or capture buffer register.
14.12.21 CCxBUFH – Compare or Capture x Buffer register H
• Bit 7:0 – CCxBUF[15:8]
These bits hold the MSB of the 16-bit compare or capture buffer register.
