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 T1CK2~T1CK0: Select TM1 Counter clock 000: fSYS/4 001: fSYS 010: fH/16 011: fH/64 100: fTBC 101: undefined 110: TCK1 rising edge clock 111: TCK1 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 fSYS is the system clock, while fH and fTBC are other internal clocks, the details of which can be found in the oscillator section. |
