7.13.9 Port B Registers
The PIP is associated with parallel I/O port B. The basic operation of the port is shown in
Figure 7-96. The registers are described in the port B description; however, the registers as
they relate to the PIP are mentioned in the following paragraphs.
7.13.9.1 PORT B ASSIGNMENT REGISTERS (PBPAR). The PBPAR is an 18-bit, mem-
ory-mapped, read-write register. To use port B pins as PIP pins, the corresponding PBPAR
bits MUST BE CLEARED, and the MODH and MODL bits in the PIP configuration register
may be configured as desired.
7.13.9.2 DATA DIRECTION REGISTER (PBDIR). The PBDIR is an 18-bit, memory-
mapped, read-write register. The description of PBDIR in 7.14.7 Port B Registers is also
valid for the PIP.
7.13.9.3 DATA REGISTER (PBDAT). PBDAT functions as the PIP data register when the
PIP is operational. This register is used to receive/transmit PIP data when the PIP is under
host software control. The description of PBDAT in 7.14.7 Port B Registers is also valid for
the PIP.
7.13.9.4 OPEN-DRAIN REGISTER (PBODR). The description of PBODR in 7.14.7 Port B
Registers is also valid for the PIP.
7.14 PARALLEL I/O PORTS
The CPM supports three general-purpose I/O ports: A, B, and C.
7-356
A character was received from the Centronics channel and was written to the receive buff-
er.
A buffer has been received on the Centronics channel.
