timer 2n modules (T2A and T2B)

The TMS370Cx6x device includes two 16-bit general-purpose timer 2 modules (T2A and T2B). The T2A or T2B

are referred to as T2n throughout this section. The T2n module contains a 16-bit resettable counter, 16-bit

compare register with associated compare logic, 16-bit capture register, and a 16-bit register that functions as

a capture register in one mode and as a compare register in the other mode. The T2n module adds additional

timers that provide event counts, input captures, and compare functions. The T2n module includes three

external-device pins that can be dedicated as timer functions or used as general-purpose I/O pins. The T2n

module is shown in Figure 11.
