6.5 Internal CSIB1 Function

6.5.1 Operation of Serial Interface

The communication I/F of the MTRC is fixed to the following settings:
• I/F:
• Mode:
• Data length:
length)
• Transfer:
• Transmission:
• Baudrate:
Cautions: 1. The internal ring oscillator of the MTRC is not synchronized to the CSIB1 SCKB1
signal. Furthermore the MTRC needs time to process the incoming commands
and data. Therefore the baudrate of the FG2 CSIB1 has to be set to maximum of
f
Ring Oscillator
2. After MTRESET release, the Ring Oscillator is uncalibrated. Therefore the maxi-
mum specified frequency deviation (especial the min. f
ibrated Ring Oscillator has to be regarded.
