Table 2-61 details the settings available to either power down or enable the prescaler associated with the

analog inputs AV, AC, and AT.

Table 2-62 details the settings available to enable the Current Monitor Block associated with the AC pin.

Table 2-63 details the settings available to configure the drive strength of the gate drive when not in high-

drive mode.

Table 2-64 details the settings available to set the polarity of the gate driver (either p-channel- or

n-channel-type devices).

Table 2-65 details the settings available to turn on the Gate Driver and set whether high-drive mode is on

or off.

Table 2-66 details the settings available to turn on and off the chip internal temperature monitor.

Note: For the internal temperature monitor to function, Bit 0 of Byte 2 for all 10 Quads must be set.
