Section 8 Bus Controller (BSC)
8.7.3
Table 8.16 shows the pins used for the byte control SRAM interface.
In the byte control SRAM interface, write strobe signals (LHWR and LLWR) are output from the
byte select strobes. The RD/WR signal is used as a write enable signal.

Function
Strobe signal indicating that the address
output on the address bus is valid when a
basic bus interface space or byte control
SRAM space is accessed
Strobe signal indicating that area n is
selected
Output enable for the SRAM when the byte
control SRAM space is accessed
Write enable signal for the SRAM when the
byte control SRAM space is accessed
