Software-Selectable Test Functionality
When bit 11 of the SYSCON register is set HIGH, all internal EPB accesses are output on the main
address and data buses as though they were external accesses to the address space addressed by CS6.
Hence CS6 handles a dual role: It is active as the strobe for internal accesses and for any accesses to
the standard address range for CS6. Additionally in this mode, the following internal signals are multi-
plexed out of the device on port pins:
NOTE:
Port E defaults to input so PE1 and PE2 has to be programmed to output mode to observe NIRQ and NFIQ
on these signals.
