I/O registers are accessed via the I/O Read (IORD) and I/O Write (IOWR, IOWX) instructions. IORD reads the selected port into
the accumulator. IOWR writes data from the accumulator to the selected port. Indexed I/O Write (IOWX) adds the contents of X
to the address in the instruction to form the port address and writes data from the accumulator to the specified port. Note that
specifying address 0 with IOWX (e.g., IOWX 0h) means the I/O port is selected solely by the contents of X.
Note:
All bits of all registers are cleared to all zeros on reset,
except the Processor Status and Control Register (
Figure 18-
1
).
All registers not listed are reserved, and should never be written by firmware. All bits marked as reserved should always be
written as 0 and be treated as undefined by reads.
