Response (bus module)
Parameter
TGL_SM
A0...A7
TIMEOUT
BUF_OFL
PRM_ERR
PRM0... PRM15
The module uses the error flags TIMEOUT, BUF_OV and PRM_ERR to re-
port errors during the parameter data exchange.
After the last parameter data has been sent to the module (MORE_PRM =
FALSE), the module checks the entire parameter set and accepts it if every-
thing is correct. Otherwise, the module returns a parameter error (PRM_ERR
= TRUE).
2.1.1.8.3.5.4 Example: Configuring Bluetooth
