Function

Port 7

5-bit N-ch open-drain I/O port

Can be specified for input or output in 1-bit units.

Can directly drive LEDs.

A pull-up resistor can be connected in 1-bit units by the mask

option.

Port 8

2-bit P-ch open-drain high-voltage output port.

Can directly drive LEDs.

A pull-down resistor can be connected in 1-bit units by the

mask option (whether VLOAD or VSS is connected can be

specified in 2-bit units).

Port 9

8-bit P-ch open-drain high-voltage output port.

Can directly drive LEDs.

A pull-down resistor can be connected in 1-bit units by the

mask option (whether VLOAD or VSS is connected can be

specified in 4-bit units).

Port 10

8-bit P-ch open-drain high-voltage output port.

Can directly drive LEDs.

A pull-down resistor can be connected in 1-bit units by the

mask option (whether VLOAD or VSS is connected can be

specified in 4-bit units).

Port 11

8-bit P-ch open-drain high-voltage I/O port.

Can be specified for input or output in 1-bit units.

Can directly drive LEDs

A pull-down resistor can be connected in 1-bit units by the

mask option (whether VLOAD or VSS is connected can be

specified in 4-bit units).

Port 12

8-bit P-ch open-drain high-voltage I/O port

Can be specified for input or output in 1-bit units.
