6.2.12 IOC51 (TCCA Counter)

The IOC51 (TCCA) is an 8-bit clock counter. It can be read, written, and cleared on any reset condition and is an Up Counter.

NOTE

TCCA timeout period [1/Fosc x (256-TCCA cnt) x 1(CLK=2)]

TCCA timeout period [1/Fosc x (256-TCCA cnt) x 2(CLK=4)]

6.2.13 IOC61 (TCCB Counter)

The IOC61 (TCCB) is an 8-bit clock counter for the least significant byte of TCCBX (TCCB). It can be read, written, and cleared on any reset condition and is an Up Counter.
