Table 9. Data 4 (read/write register. Register address = 0X5)
BIT Name Value Description
Bit 0
(LSB)
N/A 0 Reserved. Keep to “0”
Bit 1 N/A 0 Reserved. Keep to “0”
Bit 2 N/A 0 Reserved. Keep to “0”
Bit 3 OLR
1
In case of overload protection activation (OLF=1), all VSEL 1..4 bits are reset to
“0” and LNB output (V
OUT
pin) is disabled. The VSEL bits must be set again by the
master after the overcurrent condition is removed (OLF=0).
0
In case of overload protection activation (OLF=1) the LNB output (V
OUT
pin) is
automatically enabled as soon as the overload condition is removed (OLF=0) with
the previous VSEL bits setting.
Bit 4 N/A 0 Reserved. Keep to “0”
Bit 5 N/A 0 Reserved. Keep to “0”
Bit 6 THERM
1
If thermal protection is activated (OTF=1), all VSEL 1..4 bits are reset to “0” and
LNB output (V
OUT
pin) is disabled. The VSEL bits must be set again by the master
after the overtemperature condition is removed (OTF=0).
0
In case of thermal protection activation (OTF=1) the LNB output (V
OUT
pin) is
automatically enabled as soon as the overtemperature condition is removed
(OTF=0) with the previous VSEL bits setting.
Bit 7
(MSB)
N/A 0 Reserved. Keep to “0”
