Off: Input pull-up MOS is always off.
On/Off: On when the pin is in the input state, PBDDR = 0, and PBODR = 1; otherwise off.
8.13 Additional Overview for H8S/2160B and H8S/2161B
The H8S/2160B and H8S/2161B has fifteen I/O ports (ports 1 to 6, 8, 9, A, B, C, D, E, F, G), and
one input-only port (port 7).
Table 8.8 is a summary of the additional port functions. As the functions of ports 1 to 9, A, and B
are the same on the H8S/2140B, H8S/2141B, H8S/2148B, and H8S/2145B, table 8.1 provides a
summary.
Each extra port includes a data direction register (DDR) that controls input/output, and data
registers (ODR) for storing output data.
Ports C, D, E, and F have an on-chip input pull-up MOS function. On ports C, D, E, and F,
whether the input pull-up MOS is on or off is controlled by the corresponding DDR and ODR.
Ports C, D, E, F, and G can drive a single-TTL load and 30-pF-capacitive load. All I/O port pins
are capable of driving a Darlington transistor when they are in output.
The output type on port G is NMOS push-pull output. Port G can be 5-V tolerant.
When port G is used as an output pin, connect a pull-up resistor to the pin for raise an output high-
level voltage.
