I Generation of Interrupt Request from Watch Timer
• When the interval time set by the interval time select bits (WTC: WTC2 to WTC0) is reached, the
overflow flag bit (WTC: WTOF) is set to "1".
• When the overflow flag bit is set (WTC: WTOF = 1) and with interrupt enabled when the watch timer
counter overflows (carries) (WTC: WTIE = 1), an interrupt request is generated.
