ESCI Arbiter
ACLK — Arbiter Counter Clock Select Bit
This read/write bit selects the arbiter counter clock source.
Reset clears ACLK.
1 = Arbiter counter is clocked with one half of the ESCI input clock
generated by the ESCI prescaler
0 = Arbiter counter is clocked with one half of the bus clock
AFIN— Arbiter Bit Time Measurement Finish Flag
This read-only bit indicates bit time measurement has finished. Clear
AFIN by writing any value to SCIACTL. Reset clears AFIN.
1 = Bit time measurement has finished
0 = Bit time measurement not yet finished
ARUN— Arbiter Counter Running Flag
This read-only bit indicates the arbiter counter is running. Reset
clears ARUN.
1 = Arbiter counter running
0 = Arbiter counter stopped
AROVFL— Arbiter Counter Overflow Bit
This read-only bit indicates an arbiter counter overflow. Clear
AROVFL by writing any value to SCIACTL. Writing logic 0s to AM1
and AM0 resets the counter keeps it in this idle state. Reset clears
AROVFL.
1 = Arbiter counter overflow has occurred
0 = No arbiter counter overflow has occurred
ARD8— Arbiter Counter MSB
This read-only bit is the MSB of the 9-bit arbiter counter. Clear ARD8
by writing any value to SCIACTL. Reset clears ARD8.
