External Wait
Any access can be extended by an external device using the NWAIT input signal of the SMC.
The EXNW_MODE field of the MODE register on the corresponding chip select must be set to
either to “10” (frozen mode) or “11” (ready mode). When the EXNW_MODE is set to “00” (dis-
abled), the NWAIT signal is simply ignored on the corresponding chip select. The NWAIT signal
delays the read or write operation in regards to the read or write controlling signal, depending on
the read and write modes of the corresponding chip select.
27.6.7.1
Restriction
When one of the EXNW_MODE is enabled, it is mandatory to program at least one hold
cycle for the read/write controlling signal. For that reason, the NWAIT signal cannot be
used in Page Mode
(”Slow Clock Mode” on page
The NWAIT signal is assumed to be a response of the external device to the read/write
request of the SMC. Then NWAIT is examined by the SMC only in the pulse state of the
read or write controlling signal. The assertion of the NWAIT signal outside the expected
period has no impact on SMC behavior.
