79 / 124 page  PDI Description Slave Controller – ET1100 Hardware Description III-65 6.3.4 Commands The command CMD0 in the second address/command byte may be READ, READ with following Wait State bytes, WRITE, NOP, or Address Extension. The command CMD1 in the third address/command byte may have the same values: Table 61: SPI commands CMD0 and CMD1 CMD[2] CMD[1] CMD[0] Command 0 0 0 NOP (no operation) 0 0 1 reserved 0 1 0 Read 0 1 1 Read with following Wait State bytes 1 0 0 Write 1 0 1 reserved 1 1 0 Address Extension (3 address/command bytes) 1 1 1 reserved 6.3.5 Address modes The SPI slave interface supports two address modes, 2 byte addressing and 3 byte addressing. With two byte addressing, the lower 13 address bits A[12:0] are selected by the SPI master, while the upper 3 bits A[15:13] are assumed to be 000b inside the SPI slave, thus only the first 8 Kbyte in the EtherCAT slave address space can be accessed. Three byte addressing is used for accessing the whole 64 Kbyte address space of an EtherCAT slave. For SPI masters which do only support consecutive transfers of more than one byte, additional Address Extension commands can be inserted. Table 62: Address modes without (Read access without Wait state byte) Byte 2 Byte address mode 3 Byte address mode 0 A[12:5] address bits [12:5] A[12:5] address bits [12:5] 1 A[4:0] address bits [4:0] CMD0[2:0] read/write command A[4:0] address bits [4:0] CMD0[2:0] 3 byte addressing: 110b 2 D0[7:0] data byte 0 A[15:13] address bits [15:13] CMD1[2:0] read/write command res[1:0] two reserved bits, set to 00b 3 D1[7:0] data byte 1 D0[7:0] data byte 0 4 ff.
