Table 41. Flash Timing Parameters
Flash/Modem Interface Timings
The 82559 is designed to support up to 150 nanoseconds of Flash access time. The V
the Flash implementation should be connected permanently to 12 V. Thus, writing to the Flash is
controlled only by the FLWE# pin.

FLA[6:0], FLD[7:0], FLCS#, FLOE#, and FLWE# have the same functions for Flash and
modem.
FLA[8] acts as IOCHRDY asynchronous input in modem mode.
