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.
