The transfer code (TC[2:0]) output signals indicate the data transfer
code for the current bus cycle. See
codes. In single-chip mode and master mode, these pins are configured
as digital I/O (PE2, PE1, PE0) by default.
The read/write (R/W) output signal indicates the direction of the data
transfer on the bus. A logic 1 indicates a read from a slave device and a
logic 0 indicates a write to a slave device.
The address bus (A[22:0]) output signals provide the address for the
current bus transfer.
The enable byte (EB[3:0]) output signals indicate which byte of data is
valid during external cycles.
The chip select (CS[3:0]) output signals select external devices for
external bus transactions.
The output enable (OE) signal indicates when an external device can
drive data during external read cycles.
