A <Read and Clear Status> operation addressed to an unused RAM address will be

identical to a <Read Mode> operation (in case of unused RAM address, the second byte will

be equal to 00H).

The returned data byte represents the content of the register to be read.

Failures are indicated by activating the corresponding bit of the <Global Status> register.

Read device information

OC0, OC1: operating code (11 for ‘read device information mode)

The device information is stored at the ROM In the ROM memory area, the first 8 bits are

used. All unused ROM addresses will be read as ‘0’.

Note:

ROM address 3FH is unused. An attempt to access this address is recognized as a

communication line error (‘Data-in stuck to VCC’) all internal registers will be cleared

(software reset).
