4.12 16-Bit Timer Control Registers

Table 4-6 shows the registers used to control the 16-bit timers. A binary counter
(TMnBC), a compare/capture register A (TMnCA), a compare/capture register B
(TMnCB), and a timer mode register (TMnMD) is associated with each 16-bit
timer.

Note: TM4CAX, TM4CBX, TM5CAX, and TM5CBX are virtual registers used only
in double-buffer mode during PWM output. They do not exist in the hardware
and are not readable or writable. Depending on the write signal, they load the
value in the associated CA or CB register.
