Notes:
1. The max value for this parameter assumes the following worst case situation:
Value
Worst Case
0
FLASH and SRAM wait states set at “3.”
1
Host performs PCMCIA WRITE cycle at same time that Am79C930 embedded 80188 controller begins
instruction fetch cycle to FLASH memory.
2
PCMCIA WRITE cycle s posted nternal to Am79C930 device, pending the completion of the embedded 80188
controller access.
3
Host performs PCMCIA READ cycle immediately following completion of PCMCIA WRITE cycle.
4
After completion of first embedded 80188 access to FLASH, posted PCMCIA WRITE executes to SRAM;
PCMCIA READ stycle is being held in wait state.
5
After completion of posted ISA WRITE cycle, new embedded 80188 access to FLASH begins.
6
After completion of second embedded 80188 access to FLASH, PCMCIA READ cycle is allowed to proceed
onto memory bus to SRAM; host is still held in wait state.
7
At SRAM READ cycle completion, data is delivered to PCMCIA bus and wait state is exited.
2. Parameter is not included in production test.
