I've just noticed a 2 us I/O recovery time when I use the ISA bus on the STPC Industrial chip.

Does anyone know if we can disable this feature and how?

Thanks.

The data sheet says nothing else about the ISA I/O recovery, than that enabling the access to the IPC registers will make writes to these registers require longer than 2 ISACLK periods. (register 51, bit 7)
