The ST2202 builds in one chip-select signal (
CS0
) for
embedded 256K bytes mask ROM and six chip-select signals
multiplexed with PD5~0 of Port-D which are used to select
external devices on the address and data bus. There are two
options for the first 256K bytes memory which are controlled by
MMD pin. Tie MMD to ground to select normal mode and
enable internal ROM for the first 256K bytes memory. Connect
MMD to chip-select of an external device to select emulation
mode and disable internal ROM. After reset cycles, MMD
changes to an output and outputs chip-select signal
CS0
.
Refer to FIGURE 10-1 for two connections of different modes.
Two bits
CSM[1:0]
of port miscellaneous register (
PMCR
)
select four modes of CSL which define the memory size of
each external chip-select. If
CSM0
equals “1”, chip-select
signal
CS6
changes to be address signal A23 to make one
single device of 16M bytes at
CS5
possible. The address
range of
CSx
of higher number follows the range of previous
one of lower number. Refer to TABLE 10-2 for configurations of
all chip-selects in different modes.
Note: Write “1” to bit of port direction control
register
PCD
, then to bit of port
function-select register
PFD
to activate the
designated chip-select signal.
