SetParam (PARAM, VALUE)
Table 38.
The SetParam command sets the PARAM register value equal to VALUE; PARAM is the
respective register address listed in
Some registers cannot be written (see
causes the command to be ignored and the WRONG_CMD flag to rise at the end of
command byte as like as unknown command code is sent (see paragraph
Some registers can only be written in particular conditions (see
write one of those registers when the conditions are not satisfied causes the command to be
ignored and the NOTPERF_CMD flag to rise at the end of last argument byte (see
paragraph
Any attempt to set an inexistent register (wrong address value) causes the command to be
ignored and WRONG_CMD flag to rise at the end of command byte as like as unknown
command code is sent.
GetParam (PARAM)
Table 39.
This command reads the current PARAM register value; PARAM is the respective register
address listed in
Returned value is the register one at the moment of SetParam command decoding. If
register values changes after this moment the response will not be accordingly updated.
Any attempt to read an inexistent register (wrong address value) causes the command to be
ignored and WRONG_CMD flag to rise at the end of command byte as like as unknown
command code is sent.
