Response (bus module)
Parameter Value Description
TGL_SM == TGL_MS Instruction completed
A0...A7 0...(n-1) Address parameter data mirrored
TIMEOUT FALSE, TRUE Monitoring time expired
BUF_OFL FALSE, TRUE Access outside the module parameter range
PRM_ERR FALSE, TRUE Parameter/parameter set error
PRM0... PRM15 0 ...65535 Parameter data read access
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).

Process Data and Mailbox
Only parameter 0 of the Bluetooth

affects the configuration of the size of the process image and mailbox.
