CSC—Cascade Timers
0 = Timer Input signal comes from the pin.
1 = For Timer 0, Input signal is connected to Timer 3 output.
For Timer 1, Input signal is connected to Timer 0 output.
For Timer 2, Input signal is connected to Timer 1 output.
For Timer 3, Input signal is connected to Timer 2 output.
Timer 0-3 Control 1 Registers
The Timer 0-3 Control 1 (TxCTL1) registers enable/disable the timers, set the prescaler
value, and determine the timer operating mode.
