1: Enable De-bounce time is set by “(N*64-16) / f SYS ”-formula.
“N” is sum of number which is set to “1” in bit6 to bit 0. Note3:
Note1: Since an internal clock is used for de-bounce circuit, when IDLE1, STOP mode or PCM condition, the de-bounce
circuit don’t operate and also interrupt which through this circuit is not generated. When IDLE1, STOP mode or PCM
condition, set this circuit to disable (Write “0” to TSICR1) before entering HALT state.If de-bounce time is set
to “0”, signal is received after counting the 6-system clock (f
SYS
) from the condition that this circuit is set to disable.
Note2: During converting the analog input-data by using AD converter, the current flow to the normal C-MOS input-gate.
Therefore, provide its current by setting TSICR0.If the middle voltage is inputted, cut the input-signal to
C-MOS logic (P96,P97) by settig this bit.
Note3: TSICR0 is that confirming initial pen-touch. When the input-signal to C-MOS logic is blocked by
TSICR0, this bit is always “1”. Please be careful.

TSICR1=95H
