8.4 Wait State Control Signal
Either with the software using stretch value to change the required machine cycle of MOVX
instruction, the W77E058 provides another hardware signal
WAIT
to implement the wider duration of
external data access timing. This wait state control signal is the alternate function of P4.0 such that it
can only be invoked to 44-pin PLCC/QFP package type. The wait state control signal can be enabled
by setting WS (ROMMAP.7) bit. When enabled, the setting of stretch value decides the minimum
length of MOVX instruction cycle and the device will sample the
WAIT
pin at each C3 state before the
rising edge of read/write strobe signal during MOVX instruction. Once this signal being recongnized,
one more machine cycle (wait state cycle) will be inserted into next cycle. The inserted wait state
cycles are unlimited, so the MOVX instruction cycle will end in which the wait state control signal is
deactivated. Using wait state control signal allows a dynamically access timimg to a selected external
peripheral. The WS bit is accessed by the Timed Access Protection procedure.
Set WS bit ahd stretch value = 0 to enable wait signal.
