OR — Bit Error Flag
NF — Noise Error Flag
Read anytime. Write has no meaning or effect.
SCSWAI — Serial Communications Interface Stop in WAIT Mode
MIE — Freescale Interface Bus (MI Bus) Enable
MDL1, MDL0 — MI Bus delay select
This bit is set when a push field bit value on the MI Bus does not
match the bit value that was sent. This is known as an MI Bus bit
error. OR does not generate an interrupt request in MI Bus mode.
This bit is set when noise is detected on the receive line during an
MI Bus pull field.
When MIE is set, the SCI0 registers, bits and pins assume the
functionality required for MI Bus.
These bits are used to set up the delay for the start of the NRZ receive
for MI Bus operation as shown (for a 20kHz bit rate) in the following
table.
0 = No bit error has been detected.
1 = A bit error has been detected.
0 = No noise detected.
1 = Noise detected.
0 = SCI clock operates normally.
1 = Halt SCI clock generation when in WAIT mode.
0 = The SCI functions normally.
1 = MI Bus is enabled for this subsystem.
