Description
The ADDR0 is configured as an output in normal
operation. The address bus selects a location in
memory or I/O space to be read or written. This
pin is configured as an input during bus
acknowledge cycles. Drives the Chip Select/Wait
State Generator block to generate Chip Selects.
The ADDR1 pin is configured as an output in
normal operation. The address bus selects a
location in memory or I/O space to be read or
written. This pin is configured as an input during
bus acknowledge cycles. Drives the Chip Select/
Wait State Generator block to generate Chip
Selects.
The ADDR2 pin is configured as an output in
normal operation. The address bus selects a
location in memory or I/O space to be read or
written. This pin is configured as an input during
bus acknowledge cycles. Drives the Chip Select/
Wait State Generator block to generate Chip
Selects.
The ADDR3 pin is configured as an output in
normal operation. The address bus selects a
location in memory or I/O space to be read or
written. This pin is configured as an input during
bus acknowledge cycles. Drives the Chip Select/
Wait State Generator block to generate Chip
Selects.
The ADDR4 pin is configured as an output in
normal operation. The address bus selects a
location in memory or I/O space to be read or
written. This pin is configured as an input during
bus acknowledge cycles. Drives the Chip Select/
Wait State Generator block to generate Chip
Selects.
The ADDR5 pin is configured as an output in
normal operation. The address bus selects a
location in memory or I/O space to be read or
written. This pin is configured as an input during
bus acknowledge cycles. Drives the Chip Select/
Wait State Generator block to generate Chip
Selects.
