Bits 23:6 – PERBUF[17:0] Period Buffer Value
These bits hold the value of the Period Buffer register. The value is copied to PER register on UPDATE
condition.
Note: When the TCC is configured as 16-bit timer/counter, the excess bits are read zero.
Note: This bit field occupies the MSB of the register, [23:m]. m is dependent on the Resolution bit in the
Control A register (CTRLA.RESOLUTION):
CTRLA.RESOLUTION Bits [23:m]
0x0 - NONE 23:0
0x1 - DITH4 23:4
0x2 - DITH5 23:5
0x3 - DITH6 23:6 (depicted)
Bits 5:0 – DITHERBUF[5:0] Dithering Buffer Cycle Number
These bits represent the PER.DITHER bits buffer. When the double buffering is enabled, the value of this
bit field is copied to the PER.DITHER bits on an UPDATE condition.
