PEB 20534
Detailed Register Description
PU
Power Up
(all modes)
PU=’0’
The SCC is in ’power-down’ mode. The protocol engines
are switched off (standby) and no operation is performed.
This may be used to save power when SCC is not in use.
Note: The DMA Controller accessible part of the SCC
transmit FIFO requests for transmit data even in
’power-down’ mode.
PU=’1’
The SCC is in ’power-up’ mode.
SC(2..0)
Serial Port Configuration
(all modes)
This bit field selects the line coding of the serial port.
Note, that special operation modes and settings may require or exclude
operation in special line coding modes. Refer to the ’prerequisites’ in the
dedicated mode descriptions.
SC = ’000’ NRZ data encoding
SC = ’001’ Bus configuration, timing mode 1;
NRZ data encoding
SC = ’010’ NRZI data encoding
SC = ’011’ Bus configuration, timing mode 2;
NRZI data encoding
SC = ’100’ FM0 data encoding
SC = ’101’ FM1 data encoding
SC = ’110’ Manchester data encoding
SC = ’111’ Reserved
(do not use)
Note: If bus configuration mode is selected, only NRZ/NRZI data
encoding is supported.
