bit 8

CHZACT: Channel Z Active(1) bit (cleared via Soft Reset)

1 = Channel Z is passing data after TAGC

0 = Channel Z is not passing data after TAGC

bit 7

CHYACT: Channel Y Active(1) bit (cleared via Soft Reset)

1 = Channel Y is passing data after TAGC

0 = Channel Y is not passing data after TAGC

bit 6

CHXACT: Channel X Active(1) bit (cleared via Soft Reset)

1 = Channel X is passing data after TAGC

0 = Channel X is not passing data after TAGC

bit 5

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 >

20 mVPP range.

0 = AGC is inactive (Input signal is weak)

bit 4

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

bit 3

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

bit 2

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

bit 1

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

state of bit 4 of the Configuration register 0

0 = The Alarm timer is not timed out

bit 0

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

Note 1: Bit is high whenever channel is passing data. Bit is low in Standby mode.

Legend:

R = Readable bit

- n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

See Table 11-7 for the bit conditions of the AFE Status

register after various SPI commands and the AFE

Power-on Reset.
