Note 3: Interrupt requests may be generated when EINTCR1 is changed. Before doing such operation, clear the corresponding
Note 4: Bits 7 to 5 of EINTCR1 are read as "0".
Note 1: fcgck: Gear clock [Hz], fs: Low-frequency clock [Hz]
Note 2: Interrupt requests may be generated during transition of the operation mode. Before changing the operation mode, clear

interrupt enable register to "0" to disable the generation of interrupt. When the operation mode is changed from NOR-
MAL1/2 or IDLE1/2 to SLOW1/2 or SLEEP1, wait 12/fs [s] after the operation mode is changed and clear the interrupt
latch. And when the operation mode is changed from SLOW1/2 or SLEEP1 to NORMAL1/2 or IDLE1/2, wait 2/fcgck+3/
fspl [s] after the operation mode is changed and clear the interrupt latch.
After reset

Initial state or signal level "L"
Signal level "H"
An interrupt request is generated at the rising edge of the noise canceller

An interrupt request is generated at the falling edge of the noise canceller
pass signal
An interrupt request is generated at both edges of the noise canceller pass
