36.8.15 Counter Value

Note: Prior to any read access, this register must be synchronized by the user by writing the according TCC Command value to the Control B Set register (CTRLBSET.CMD = READSYNC).

Note: This register is write-synchronized: SYNCBUSY.COUNT must be checked to ensure the COUNT register synchronization is complete.

Bits 23:0 – COUNT[23:0] Counter Value

These bits hold the value of the counter register.

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 (depicted)
0x1 - DITH4	23:4
0x2 - DITH5	23:5
0x3 - DITH6	23:6
