Clearing the bit to zero restores normal counter operation. When in a Pause condition the TM will remain powered up and continue to consume power. The counter will retain its residual value when this bit changes from low to high and resume counting from this value when the bit changes to a low value again. Bit 6~4 T0CK2~T0CK0: Select TM0 Counter clock 000: f SYS/4 001: f SYS 010: f H/16 011: f H/64 100: f TBC 101: undefined 110: TCKn rising edge clock 111: TCKn falling edge clock These three bits are used to select the clock source for the TM. Selecting the Reserved clock input will effectively disable the internal counter. The external pin clock source can be chosen to be active on the rising or falling edge. The clock source f SYS is the system clock, while fH and f TBC are other internal clocks, the details of which can be found in the oscillator section. Bit 3 T0ON: TM0 Counter On/Off Control 0: Off 1: On This bit controls the overall on/off function of the TM. Setting the bit high enables the counter to run, clearing the bit disables the TM. Clearing this bit to zero will stop the counter from counting and turn off the TM which will reduce its power consumption. When the bit changes state from low to high the internal counter value will be reset to zero, however when the bit changes from high to low, the internal counter will retain its residual value. If the TM is in the Compare Match Output Mode then the TM output pin will be reset to its initial condition, as specified by the T0OC bit, when the T0ON bit changes from low to high.
