Short Read D1 Memory (Code D4hex) The Short Read D1 Memory command works similar to the Read D1 Memory command but with the code Dhex fol- lowed by a 4hex. Example: Read 16 bits of D1:123 has the following I2C protocol: <DW 68 d4 00 read 16 bits from D1 00 01 1 word to be read 01 23 start address <DW 69 DR dd dd> start reading 3.3.1.8. Write D0 Memory (Code Ehex) With the Write D0 Memory command n 20-bit memory cells in D0 can be initialized with new data. Example: Write 80234hex to D0:456 has the following I 2C protocol: <DW 68 e0 00 write D1 memory 00 01 1 word to write 04 56 start address 00 08 value = 80234hex 02 34> S DW A W $69 A W S DW A W $68 A W d,4 A 0,0 A W d3,d2 A d1,d0 A W 2) get memory value S DR A W 1) send command n3,n2 A n1,n0 A W a3,a2 A a1,a0 A W P P ...repeat for n data values... d3,d2 A d1,d0 N W S DW A W $68 A W e,0 A 0,0 A W n3,n2 A n1,n0 A W d3,d2 A d1,d0 A W ...repeat for n data values... 0,0 A 0,d4 A W d3,d2 A d1,d0 A W P 0,0 A 0,d4 A W a3,a2 A a1,a0 A W |
