Description
Bit 0
16-Bit Memory Delay Inhibit. When this bit is set to "0" if 16-bit access (bit7 of System Memory
Address # Mapping Start High Byte Register is "1"),
WE and OE signals are output by one-stage
synchronization of
IMEMW and IMEMR, with the falling edge of ISYSCLK. When this bit is set to "1"
WE and OE signals are always output asynchronously with ISYSCLK. The timing diagram of SCLK
synchronization of
WE, OE is shown below.
