7.26 Port Q (PQ0~PQ3)

PQ read
(function control)
The port Q is a general-purpose, 4-bit input/output port. For this port, inputs and outputs
can be specified in units of bits. Outputs can be set by using the control register PQCR and
the function register PQFC1. A reset allows all bits of the PQ, PQCR and PQFC1 to be
cleared to "0," and the port Q to be put in output disable mode.
Besides the input/output port function, the port Q performs other functions: PQ0 and PQ2
function as DREQ2 and DREQ3. PQ1 and PQ3 function as DACK2 and DACK3.
