Sign of signal B position sensor 2 (B2P, B2N). If
the value is positive (B2P > B2N) B_2 is 1, if the
value is negative (B2P < B2N) B_2 is 0.
Sign of signal B position sensor 1 (B1P, B1N). If
the value is positive (B1P > B1N) B_1 is 1, if the
value is negative (B1P < B1N) B_1 is 0.
Over-current output of phase V, active low. If
IVP-IVN is greater then the positive limiting value
or less than the negative limiting value, U_ILIM
becomes 0.
Sign of phase V current signal (IVP, IVN). If the
value is positive (IVP > IVN) V_COMP is 1, if the
value is negative (IVP < IVN) V_COMP is 0.
Over-current output of phase W, active low. If
IWP-IWN is greater then the positive limiting
value or less than the negative limiting value,
U_ILIM becomes 0.
Sign of phase W current signal (IWP, IWN). If
the value is positive (IWP > IWN) W_COMP is 1,
if the value is negative (IWP < IWN) W_COMP
is 0.

ADCLK
DI
Clock for the A/D converters. The nominal clock
frequency is 1.25MHz.
Start signal for the A/D converter, active low. The
first rising clock edge of ADCLK, when ADCONV
is 0, starts the conversion.
Sample/hold control for sampling the position
sensor signals. If the value is 1, the signals are
sampled, if it is 0 they are stored.
Serial input signal for programming the D/A
converter for setting the limit value of the current
signals for the input voltage range of the A/D
converters and for the input multiplexer of the
A/D converters.
Conversion is executing, active low
Test pin, do not connect to in normal operation.

Sign of phase U current signal (IUP, IUN). If the
value is positive (IUP > IUN) U_COMP is 1, if
the value is negative (IUP < IUN) U_COMP is 0.
Over-current output of phase U, active low. If
IUP-IUN is greater then the positive limiting value
or less than the negative limiting value, U_ILIM
becomes 0.
Sign of signal A position sensor 1 (A1P, A1N). If
the value is positive (A1P > A1N) A_1 is 1, if the
value is negative (A1P < A1N) A_1 is 0.
Sign of signal A position sensor 2 (A2P, A2N). If
the value is positive (A2P > A2N) A_2 is 1, if the
value is negative (A2P < A2N) A_2 is 0.
