Confirm commands

Confirm commands are sent by the ST7580 to the external host after a previous request

command, if the request itself has been correctly executed.

Table 11 lists confirm command codes: their syntax and data fields are explained in the next

paragraphs.

Error commands

Error commands are sent by the ST7580 to the external host after a previous request

command, if it has not been executed or if an error has occurred while it was executing.

The data field of the correspondent local frames presents a same syntax for all error

command codes, with the exception of CMD_SyntaxError (Section 3.3.23). It is composed

of 1 byte and it is coded in accordance with the values listed in Table 14.
