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<DBC7>) before entering HALT state.If de-bounce time is set
to "0", signal is received after counting the 6-system clock (f
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<INGE>.If the middle voltage is inputted, cut the input-signal to
C-MOS logic (P96,P97) by settig this bit.
Note3: TSICR0<PTST> is that confirming initial pen-touch. When the input-signal to C-MOS logic is blocked by
TSICR0<INGE>, this bit is always "1". Please be careful.
Ex:
TSICR1=95H →N = 64 + 4 + 1 = 69
