Notes 1. When changing the clock selected for fCLK (by changing the system clock control register (CKC) value),
stop the timer array unit (TT0 = 00FFH, TT1 = 000FH).
2. Only in the case of SDIV=0, CCSmn=1 and TISmn=1, continuously use of TAUm is allowed, even when
changing CPU clock. However, the following limitation is existing.
• When changing CPU clock, source clock decrease/increase occurs as follows.
Main clock → Subsystem clock (CSS = 0→1): −1 clock
Subsystem clock → Main clock (CSS = 1→0): +1 clock
Caution Be sure to clear bits 15 to 8 to “0”.
Remarks 1. fCLK: CPU/peripheral hardware clock frequency
2. k = 0, 1
3. mn: Unit number + Channel number
m = 0, 1, mn = 00 to 07, 10 to 13
