This input signal indicates that the external data transfer is complete.
During a read cycle, when the processor recognizes TA, it latches the
data and then terminates the bus cycle. During a write cycle, when the
processor recognizes TA, the bus cycle is terminated. This signal is an
input in master and emulation modes. This function is not used in single-
chip mode and its pin defaults to digital I/O.
This signal indicates an error condition exists for the bus transfer. The
bus cycle is terminated and the central processor unit (CPU) begins
execution of the access error exception. This signal is an input in master
and emulation modes. This function is not used in single-chip mode and
its pin defaults to digital I/O.
These output signals provide chip select support in emulation mode.
These output signals indicate the data transfer code for the current bus
cycle. These signals are enabled by default only in emulation mode. See
Table 12-2. PEPAR Reset
This 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.
These output signals provide the address for the current bus transfer.
