The Flash memories are 16-bit wide when it is in Program Memory space and are 8-bit wide
when it is in the Data Space. When the Flash memory is configured in both “Program
Space” and “Data Space,” the Flash will drive 16-bit in a PSEN cycle and operates as an 8-
bit memory in READ or WRITE cycle.
The SRAM, csiop, and external device are always in 8-bit data space.
Table 105. Data width in different bus cycles
x = NA
Runtime control register definitions (csiop)
The 39 csiop registers are defined in
address offset (specified in
in PSDsoft Express. Do not write to unused locations within the csiop block of 256 registers,
they should remain logic zero.

106. The 8032 can access each register by the
Secondary
MCU I/O input mode. Read to
obtain current logic level of pins
on Ports A, B, C, or D. No
WRITEs.
Selects MCUI/O or Latched
Address Out mode. Logic 0 =
MCU I/O, 1 = 8032 Addr Out.
Write to select mode. Read for
status.
MCU I/O output mode. Write to
set logic level on pins of Ports
A, B, C, or D. Read to check
status. This register has no
effect if a port pin is driven by
an OMC output from PLD.
MCU I/O mode. Configures
port pin as input or output.
Write to set direction of port
pins.
Logic 1 = out, Logic 0 = in.
Read to check status.
