A/T90FJR
the PC Card standard whenever the host microprocessor accesses one of the modules. The
control signals activated depend on the access type chosen in the Module Control Register with
ACS[1..0]. The read and write signals active level duration is configured in the memory access
cycle time registers. The CIMaX receives RDY/IRQ# from the module and retransmits the
interruption to the host microprocessor. The module can also send a WAIT# request that is also
transmitted to the host microprocessor in addition to the wait states already generated due to the
read and write duration.
