8.7
The port B is an 8-bit I/O port also functioning as address bus (A15 to A8) output pins. The port B
has the following registers.
Note: When the USB is used while the E6000 emulator is used, the AE3 to AE0 bits in PFCR
• Port B data direction register (PBDDR)
• Port B data register (PBDR)
• Port B register (PORTB)
• Port B pull-up MOS control register (PBPCR)
8.7.1
PBDDR specifies input or output for the pins of the port B.
Since PBDDR is a write-only register, the bit manipulation instructions must not be used to write
PBDDR. For details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.

must be set so that the PB1 and PB0 pins output addresses A9 and A8. This note applies to
both the H8S/2218 Group and H8S/2212 Group.

Modes 4 to 6:
If address output is enabled by the setting of bits AE3 to
AE0 in PFCR, the corresponding port B pins are address
outputs. When address output is disabled, setting a
PBDDR bit to 1 makes the corresponding port B pin an
output port, while clearing the bit to 0 makes the pin an
input port.
Mode 7:
Setting a PBDDR bit to 1 makes the corresponding port B
pin an output port, while clearing the bit to 0 makes the
pin an input port.
