Atmel AVR XMEGA D
• Bit 7:0 – PERBUF[7:0]
These bits hold the LSB of the 16-bit period buffer register.
12.11.19 PERBUFH – Timer/Counter Period Buffer H
• Bit 7:0 – PERBUF[15:8]
These bits hold the MSB of the 16-bit period buffer register.
12.11.20 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 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.
12.11.21 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.
