3.2.5.1. Extended I/O
In addition to the nominal I/O area, an extended I/O area is reserved in the MEC
memory map. The MEC does not provide any chip select signals for the extended I(O
area, i.e. address decoding must be implemented with external logic. The extended I/O
area is BUSRDY* controlled with the same number of waitstates as the nominal I/O
area. The number of waitstates is however always at least one even if the I/O area
waitstate value has been programmed to zero. The same no. of waitstates and parity
option as for I/O area 3 apply.
