Description
7 ZONE3_VDD. Is set to 1 to configure Zone3 Temperature Channel as a VDD channel. In this case, when the VDD3
supply is off, monitoring of this channel is disabled and all the status bits are reset to 0 (except for the flags asso-
ciated with the channel’s critical limit). Monitoring is enabled and status bits are released, 182 ms after the VDD3
supply is turned back on.
0: Channel is not a VDD channel (default)
1: Channel is a VDD channel
6 ZONE2_VDD. Is set to 1 to configure Zone2 Temperature Channel as a VDD channel. In this case, when the VDD3
supply is off, monitoring of this channel is disabled and all the status bits are reset to 0 (except for the flags asso-
ciated with the channel’s critical limit). Monitoring is enabled and status bits are released, 182 ms after the VDD3
supply is turned back on.
0: Channel is not a VDD channel (default)
1: Channel is a VDD channel
5 ZONE1_VDD. Is set to 1 to configure Zone1 Temperature Channel as a VDD channel. In this case, when the VDD3
supply is off, monitoring of this channel is disabled and all the status bits are reset to 0 (except for the flags asso-
ciated with the channel’s critical limit). Monitoring is enabled and status bits are released, 182 ms after the VDD3
supply is turned back on.
0: Channel is not a VDD channel
1: Channel is a VDD channel (default)
4 12V_VDD. Is set to 1 to configure 12V Voltage Channel as a VDD channel. In this case, when the VDD3 supply is
off, monitoring of this channel is disabled and all the status bits are reset to 0. Monitoring is enabled and status bits
are released, 182 ms after the VDD3 supply is turned back on.
0: Channel is not a VDD channel (default)
1: Channel is a VDD channel
3 5V_VDD. Is set to 1 to configure 5V Voltage Channel as a VDD channel. In this case, when the VDD3 supply is off,
monitoring of this channel is disabled and all the status bits are reset to 0. Monitoring is enabled and status bits are
released, 182 ms after the VDD3 supply is turned back on.
0: Channel is not a VDD channel (default)
1: Channel is a VDD channel
2 3.3V_VDD. Is set to 1 to configure 3.3V Voltage Channel as a VDD channel. In this case, when the VDD3 supply is
off, monitoring of this channel is disabled and all the status bits are reset to 0. Monitoring is enabled and status bits
are released, 182 ms after the VDD3 supply is turned back on.
0: Channel is not a VDD channel (default)
1: Channel is a VDD channel
1 Vccp_VDD. Is set to 1 to configure Vccp Voltage Channel as a VDD channel. In this case, when the VDD3 supply
is off, monitoring of this channel is disabled and all the status bits are reset to 0. Monitoring is enabled and status
bits are released, 182 ms after the VDD3 supply is turned back on.
0: Channel is not a VDD channel.
1: Channel is a VDD channel (default)
0 2.5V_VDD. Is set to 1 to configure 2.5V Voltage Channel as a VDD channel. In this case, when the VDD3 supply is
off, monitoring of this channel is disabled and all the status bits are reset to 0. Monitoring is enabled and status bits
are released, 182 ms after the VDD3 supply is turned back on.
0: Channel is not a VDD channel (default)
1: Channel is a VDD channel
