RL78/G1H CHAPTER 7 TIMER ARRAY UNIT

Figure 7 - 10 Format of Timer clock select register m (TPSm) (1/2)
Note When changing the clock selected for fCLK (by changing the system clock control register (CKC) value), stop
timer array unit (TTm = 000FH).
The timer array unit must also be stopped if the operating clock (f
MCK) or the valid edge of the signal input
from the TImn pin is selected.
Caution 1. Be sure to clear bits 15, 14, 11, 10 to “0”.
Caution 2. If f
CLK (undivided) is selected as the operation clock (CKmk) and TDRnm is set to 0000H (n = 0 or 1, m
= 0 to 3), interrupt requests output from timer array units cannot be used.
Remark 1.
fCLK: CPU/peripheral hardware clock frequency
Remark 2. Waveform of the clock to be selected in the TPSm register which becomes high level for one period of fCLK
from its rising edge (m = 1 to 15). For details, see 7.5.1 Count clock (fTCLK).
Address: F01B6H, F01B7H (TPS0), F01F6H, F01F7H (TPS1) After reset: 0000H R/W
