TC3DRA
TC3DRB
(001CH)
(001DH)
(001EH)
TC3CR
(TC3DRA and TC3DRB).
The TimerCounter 3 is controlled by the TimerCounter 3 control register (TC3CR) and two 8-bit timer registers
Note 1: fc: High-frequency clock [Hz], *: Don’t care
Note 2: Set the source clock when TimerCounter stops (TC3CR<TC3S> = 0).
Note 3: To set the timer registers, the following relationship must be satisfied.
Note 4: When the read instruction is executed to TC3CR, the bit 5 and 7 are read as a don’t care.
Note 5: Do not program TC3DRA when the timer is running (TC3CR<TC3S> = 1).
