5.2.5 selection bit 10, Combination of Motor Control and Half bridge Control
All half bridge outputs, that have been directly addressed once by setting the "Selection" bit to 0
direct access mode. Thus they will not be switched to tristate mode regardless of any motor control command.
The status will change when the same half bridge gets addressed by a motor control command. Status change
works in both directions, the last valid command defines whether the half bridge output is under direct access or
is part of a motor driver.
5.2.6 Motor stop bit
The "SwitchStop" bit allows halting a motor before it has reached its final position. The motor will be stopped after
the next ripple has been detected (or timeout has been expired in case of motor stall). Pulses will be counted dur-
ing braking, as in any normal case, and after no ripples have been detected for 100ms, DRB will be activated and
the actual position is available via SPI.
No position command has to be transferred when bit 11 is set to 1
to 1 byte.
5.2.7 gain bits
The gain bits GainNorm[1:0] or GainBreak[1:0], respectively, are used to match the input amplifier's gain with the
motors connected to the IC independently for normal mode and for break mode:
5.2.8 pulse threshold bits
The pulse threshold bits PulsThNorm[2:0] or PulsThBreak[2:0], respectively, control the threshold voltage of the
pulse detector independently for normal mode and for break mode. The threshold can be varied according to the
following table:
