Note:
Note 1: fc: High-frequency clock [Hz], fs: Low-frequency clock [Hz]
Note 2: The timer register consists of two shift registers. A value set in the timer register is put in effect at the rising
Note 3: Set the mode, source clock, PPG control and timer F/F control when TC1 stops (TC1S
Note 4: Auto capture can be used in only timer, event counter, and window modes.
Note 5: Values to be loaded to timer registers must satisfy the following condition.
Note 6: Always write “0” to TFF1 except PPG output mode.
Note 7: Writing to the TC1DRB is not possible unless TC1 is set to the PPG output mode.
Note 8: On entering STOP mode, the TC1 start control (TC1S) is cleared to “00” automatically. So, the timer stops.
Note 9: Use the auto-capture function in the operative condition of TC1. A captured value may not be fixed if it's

Therefore, the lower byte must be written before the upper byte (It is recommended that a 16-bit access
instruction be used in writing). Writing only the lower data (TC1DRAL and TC1DRBL) does not put the
setting of the timer register in effect.
