The CY7C637xxC microcontrollers provide 256 bytes of data
RAM. In normal usage, the SRAM is partitioned into four
areas: program stack, data stack, user variables and USB
endpoint FIFOs as shown below.
Data Memory Organization
8.3
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 accumu-
lator 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
I/O Register Summary
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 20-1
).
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.
