Table 24: READSTAT register

READSTAT
Bit
Bit name
Default
Access
Bit description
7:6
STATE[1:0]
0x0
R
“00” initialized
“01” sleep
“10” active
“11” deep sleep
5
TEST_FLAG
0x0
R
When this flag is set, a device is either in TEST mode or OTP
CRC1 is wrong (= OTP error)
4
OV_FLAG
0x0
RC
Will be set when device detected an overvoltage condition. Will be
automatically cleared after readout and set again if error still exists
(Sticky flag).
3
CE_FLAG
0x0
RC
When set, device detected an error in a received telegram, either
CRC error (when enabled in “SETUP” register) or length error or
other error at protocol or data link layer. Telegrams are always
checked, no matter is a device had been addressed by a telegram
or not. Will be automatically cleared after readout and set again if
error still exists (Sticky flag).
2
LOS_FLAG
0x0
RC
Will be “1” when in any of the LED channels either a short or open
defect has been detected. Will be automatically cleared after
readout and set again if error still exists (Sticky flag).
1
OT_FLAG
0x0
RC
Will be set when device detected overtemperature condition. Will
be automatically cleared after readout and set again if error still
exists (Sticky flag).
0
UV_FLAG
0x0
RC
Will be set when device detected an undervoltage condition. Will
be automatically cleared after readout and set again if error still
exists (Sticky flag).
Permanent clearing of LOS_FLAG requires a read-out of LEDSTCHN register beforehand, as
the LOS_FLAG signals the presence of any high flag in that register.
