These bits determine which temperature source controls the DRIVE2 output.
00 = Local temperature controls DRIVE2.
01 = Remote 1 temperature controls DRIVE2.
10 = Remote 2 temperature controls DRIVE2.
11 = DRIVE2 full speed.
These bits determine which temperature source controls the DRIVE1 output.
00 = Local temperature controls DRIVE1.
01 = Remote 1 temperature controls DRIVE1.
10 = Remote 2 temperature controls DRIVE1.
11 = DRIVE1 full speed.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 0.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 1.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 0.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 1.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 0.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to

A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 1.
A 1 disables the corresponding interrupt status bit from causing the interrupt output to
be set. The status bit is not affected. Default = 0.
Unused.
A 1 disables the corresponding interrupt status bit, preventing it from causing the
interrupt output. The status bit is not affected. Default = 1.
A 1 disables the corresponding interrupt status bit, preventing it from causing the
interrupt output. The status bit is not affected. Default = 0.
A 1 disables the corresponding interrupt status bit, preventing it from causing the
interrupt output. The status bit is not affected. Default = 0. This bit has no effect in
ALERT comparator mode, because the corresponding status bit does not generate an
ALERT in that mode.
Unused.
