Section 8 I/O Ports
8.12.5
Port B has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
When a pin is designated as an on-chip peripheral module output pin, the input pull-up MOS is
always off.
Table 8.7 summarizes the input pull-up MOS states.

Mode
1, 2, 3 (EXPE = 1) with
ABW in WSCR = 0
1, 2, 3 (EXPE = 1) with
ABW in WSCR = 1, or 2, 3
(EXPE = 0)
Legend:

On/Off: On when the pin is in the input state, PBDDR = 0, and PBODR = 1; otherwise off.
8.13
The H8S/2160B and H8S/2161B has fifteen I/O ports (ports 1 to 6, 8, 9, A to 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 to E, and F have an on-chip input pull-up MOS function. On ports C to F, whether the
input pull-up MOS is on or off is controlled by the corresponding DDR and ODR.
Ports C to 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.
