Must be cleared for normal operation. When set, the
SG_TST output exposes digital test values, and the
TEST_ANA output exposes analog test values. Test value
selection is controlled by SGT1 and SGT0:
TEST_ANA:
%00: anatest_2vth,
%01: anatest_dac_out,
%10: anatest_vdd_half.
SG_TST:
%00: comp_A,
%01: comp_B,
%10: CLK,
%11: on_state_xy
%00: Minimum
%01: Minimum temperature compensation mode.
%10: Medium temperature compensation mode.
%11: Maximum
In temperature compensated mode (tc), the MOSFET gate
driver strength is increased if the overtemperature
warning temperature is reached. This compensates for
temperature dependency of high-side slope control.
%00: Minimum.
%01: Minimum.
%10: Medium.
%11: Maximum.
0: Short to GND protection is enabled.
1: Short to GND protection is disabled.
%00: 3.2µs.
%01: 1.6µs.
%10: 1.2µs.
%11: 0.8µs.
0: Enable STEP/DIR operation.
1: Disable STEP/DIR operation. SPI interface is used to
move motor.
0: Full-scale sense resistor voltage is 305mV.
1: Full-scale sense resistor voltage is 165mV.
(Full-scale refers to a current setting of 31 and a DAC
value of 255.)
