7.2.3.2 Writing control bits
Some device functions can be executed by setting bits directly in bytes 6 and 7 (control
bytes) of the write window.
Action of the master Slave reaction
Set bits in the control byte .
Function is executed.
Reset bits in the control byte .
7.2.4 Waiting for the result of the action
When an action requiring more time is started, the end of execution can also be waited
for.
Action of the master Slave reaction
For setting bits, see Chapter 7.2.2.3 or
7.2.3.2 .
Set the CmdBusy bit.
Function is executed.
In the event of an error: Set the
CmdError bit and the LastError byte.
If the function is executed or timeout:
reset the
CmdBusy bit.
Wait until CmdBusy = 0.
Check the CmdError bit.
If CmdError is set:
Evaluate the LastError (for function
number 4, see Chapter 7.2.5.5 )
Set the ResetError bit (for function
number 121, see Chapter 7.2.5.14 ).
The ResetError bit is reset.
The CmdError bit is reset.
7.2.5 Function numbers
Function numbers are written to MOSI by the master (SPS) and reflected in MISO by the
PR 5211.
