CHZACT: Channel Z Active
1 = Channel Z is passing data after T
0 = Channel Z is not passing data after T
CHYACT: Channel Y Active
1 = Channel Y is passing data after T
0 = Channel Y is not passing data after T
CHXACT: Channel X Active
1 = Channel X is passing data after T
0 = Channel X is not passing data after T
AGCACT: AGC Active Status bit (real time, cleared via Soft Reset)
1 = AGC is active (Input signal is strong). AGC is active when input signal level is approximately >
0 = AGC is inactive (Input signal is weak)
WAKEZ: Wake-up Channel Z Indicator Status bit (cleared via Soft Reset)
1 = Channel Z caused a AFE wake-up (passed 64 clock counter)
0 = Channel Z did not cause a AFE wake-up
WAKEY: Wake-up Channel Y Indicator Status bit (cleared via Soft Reset)
1 = Channel Y caused a AFE wake-up (passed 64 clock counter)
0 = Channel Y did not cause a AFE wake-up
WAKEX: Wake-up Channel X Indicator Status bit (cleared via Soft Reset)
1 = Channel X caused a AFE wake-up (passed 64 clock counter)
0 = Channel X did not cause a AFE wake-up
ALARM: Indicates whether an Alarm timer time-out has occurred (cleared via read “Status Register
command”)
1 = The Alarm timer time-out has occurred. It may cause the ALERT output to go low depending on the
0 = The Alarm timer is not timed out
PEI: Parity Error Indicator bit – indicates whether a Configuration register parity error has occurred (real
time)
1 = A parity error has occurred and caused the ALERT output to go low
0 = A parity error has not occurred
Legend:
R = Readable bit
- n = Value at POR
