• Bit 7:0 - PER[7:0]
These bits holds the 8 LSB of the 16-bit Period register.
The CCxH and CCxL register pair represents the 16-bit value CCx.
These 16-bit registers have two functions dependent of mode of operation. For capture opera-
tion these registers constitute the second buffer level and access point for the CPU. For
compare operation these registers are all continuously compared to the counter value. Normally
the outputs form the comparators are then used for generating waveforms.
CCx are updated with the buffer value from the corresponding CCxBUF register when an
UPDATE condition occurs.
• Bit 7:0 - CCx[15:8]
These bits holds the 8 MSB of the 16-bit Compare or Capture register.
• Bit 7:0 - CCx[7:0]
These bits holds the 8 LSB of the 16-bit Compare or Capture register.
The PERBUFH and PERBUFL register pair represents the 16-bit value PERBUF. This 16-bit
register serves as the buffer for the period register (PER). Accessing this register using CPU will
affect the PERBUFV flag.
