18.3

Read Single Block

When receiving the Read Single Block command, the LRI64 reads the requested block and

sends back its 8-bit value in the response. The Option_Flag is supported. The Read Single

Block can be issued in both addressed and non addressed modes.

The request frame (Figure 26) contains:

●

Request flags (Table 3 and Table 4)

●

Read Single Block command code (20h, Table 9)

●

Unique ID (Optional)

●

Block number

●

2-byte CRC (Figure 15)

If there is no error, at the LRI64, the response frame (Figure 27) contains:

●

Response flags (Table 6)

●

Block locking status, if Option_Flag is set

●

1 byte of block data (Table 10)

●

2-byte CRC (Figure 15)

Otherwise, if there is an error, the response frame (Figure 28) contains:

●

Response flags (01h, Table 6)

●

Error code (0Fh, Table 7)

●

2-byte CRC (Figure 15)
