Signal Name:
Signal Description:
Signal Type:
In non–multiplexed bus operation (MUX = 0), serves as the address bus. In multiplexed bus operation (MUX =
1), these pins are not used and should be tied low.
Signal Name:
RD*(DS*)/SCLK
Signal Description:
Read Input - Data Strobe / Serial Port Clock
Signal Type:
Input
RD* and DS* are active low signals. DS active HIGH when MUX = 0. See bus timing diagrams.
Signal Name:
CS*
Signal Description:
Chip Select
Signal Type:
Input
Must be low to read or write to the device. CS* is an active low signal.
Signal Name:
ALE(AS)/A5
Signal Description:
Address Latch Enable(Address Strobe) or A6
Signal Type:
Input
In non–multiplexed bus operation (MUX = 0), serves as the upper address bit. In multiplexed bus operation
(MUX = 1), serves to de-multiplex the bus on a positive–going edge.
Signal Name:
WR*(R/W*)/SDI
Signal Description:
Write Input(Read/Write) / Serial Port Data Input
Signal Type:
Input
WR* is an active low signal.
5.1.5 SERIAL PORT CONTROL PINS
Signal Name:
SDO
Signal Description:
Serial Port Output
Signal Type:
Output
Data at this output can be updated on the rising or falling edge of SCLK
Signal Name:
SDI
Signal Description:
Serial Port Data Input
Signal Type:
Input
Data at this input can be sampled on the rising or falling edge of SCLK
Signal Name:
ICES
Signal Description:
Input Clock Edge Select
Signal Type:
Input
Used to select which SCLK clock edge will sample data at SDI
Signal Name:
OCES
Signal Description:
Output Clock Edge Select
Signal Type:
Input
A0 TO A4
