ICS1522
NOTES:
1. R/Wn, READ=1 and WRITE=0
2. Address and data transmitted least significant bit first
3. 16 Positive-edge clocks required for complete data read/write (1-R/Wn, 3-Address,
11-Data, and 1 load data W/SELn HIGH)
4. SELn’s positive and negative transitions must occur on the same state of SCLK
5. An ICS1522 read consists of two consecutive cycles (1st cycle - SDATA is an input,
2nd cycle - SDATA is an output)
