12.11.19 PERBUFL - Timer/Counter Period Buffer L
12.11.20 CCxBUFH - Compare or Capture x Buffer Register H
12.11.21 CCxBUFL - Compare or Capture x Buffer Register L
8210B–AVR–04/10
• Bit 7:0 - PERBUF[15:8]
These bits holds the 8 MSB of the 16-bit Period Buffer register.
• Bit 7:0 - PERBUF[7:0]
These bits holds the 8 LSB of the 16-bit Period Buffer register.
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 register using CPU will affect the corresponding CCxBV status bit.
• Bit 7:0 - CCxBUF[15:8]
These bits holds the 8 MSB of the 16-bit Compare or Capture Buffer register.
• Bit 7:0 - CCxBUF[7:0]
These bits holds the 8 LSB of the 16-bit Compare or Capture Buffer register.
