(3) Timer counter control register (TC2)
The timer counter control register (TC2) is an 8-bit register that controls the timer counter (channel 2). Figure
6-30 shows the format of this register.
This register controls timer output enable carrier generator mode used in combination with the timer counter
(channel 1).
TC2 is set by an 8- or 4-bit manipulation instruction and bit manipulation instruction.
All the bits of TC2 are cleared to 0 when the internal reset signal is asserted.
