O/I/O
Write Byte Enable 0 / Address Bus Bit 4 / Byte Enable 0. When the
403GC is bus master, the write byte enable outputs, WBE0:3, select
the active byte(s) in a memory write access to SRAM.
The byte enables can also be programmed as read/write byte
enables, depending on the mode set in the IOCR. Note 3 on page
33 summarizes the functional and timing differences in these signals
when programmed as read/write byte enables.
For 8-bit memory regions, WBE2 and WBE3 become address bits
30 and 31 and WBE0 is the byte-enable line. For 16-bit memory
regions, WBE2 and WBE3 become address bits 30 and 31 and
WBE0 and WBE1 are the high byte and low byte enables, respec-
tively. For 32-bit memory regions, WBE0:3 are byte enables for
bytes 0-3 on the data bus, respectively. When the 403GC is not bus
master, WBE0:1 are used as the A4:5 inputs (for bank register
selection) and WBE2:3 are used as the A30:31 inputs (for byte
selection and page crossing detection).
