Structure of the parameter field
Table 8-12 continued:
08H Parameter 1 The following bits are set depending on the error:
Bit no. 0 = 1: QVZ in initialization
Bit no. 1 = 1: PARE in initialization
Bit no. 2 = 1: content of the memory card too large
Bit no. 3 = 1: operating system error
Bit no. 4 = 1: incorrect block ID
Bit no. 5 = 1: incorrect block delimiter
Bit no. 6 reserved
Bit no. 7 reserved
Bit no.8 = 1: DB 0 changed since last COLD RESTART
Bits no. 9
to 15
reserved
Parameter 2 error address high, (when bit 2, 4 or 5 of parameter 1 = ’1’
Parameter 3 error address low, (when bit 2, 4 or 5 of parameter 1 = ’1’
09H Parameter 1 Opcode "GX DX" or "G DB" (indicates the block type)
Parameter 2 block number
