P0B0-P0B3: I/O (bit I/O)

P0C0-P0C3: I/O (group I/O)

P0D0-P0D3: I/O (group I/O)

P1A0: Input or output selectable by mask option

P0B0-P0B3: Input

P0C0-P0C3: Output

P0D0-P0D3: Output

RESET pin is internally pulled down by

occurrence of the internal reset signals on the

left, and reset takes place (usually, RESET pin

is pulled up).

Low level is output from WDOUT pin by

occurrence of the internal reset signals on the

left, and reset takes place if the WDOUT pin

is externally connected to the RESET pin.

<1> When any of pins P0A0-P0A3 goes low

<2> When P0B0-P0B3, P0C0-P0C3, and

P0D0-P0D3 are used as input pins and

any of them goes low

<3> When the interrupt request (IRQ) of an

interrupt for which IP flag is set is

generated at rising or falling edge of INT pin

When any of P0A0-P0A3 or P0B0-P0B3 goes

low

Selected by mask option

<1> If carrier generation clock (RfX) is fX/2:

7.8 kHz to 1 MHz

<2> If carrier generation clock (RfX) is fX:

15.6 kHz to 2 MHz

7.8 kHz to 1 MHz
