The format for all instructions sent to the device is a
logical “1” start bit, a 2 ? bit (or 4 ? bit) opcode, 7 ? bit address
(CAT93C57) / 8 ? bit address (CAT93C56) (an additional bit
Table 10. INSTRUCTION SET
when organized X8) and for write operations a 16 ? bit data
field (8 ? bit for X8 organizations). The instruction format is
shown in Instruction Set table.
