5.1 General Configuration Registers
GENERAL CONFIGURATION REGISTERS (0X00…0X1F)
R/W Addr n Register
Description / bit names
Bit GCONF – Global configuration flags
0..2 Reserved, set to 0
3 poscmp_enable
0: Outputs INT and PP are tristated.
1: Position compare pulse (PP) and interrupt output
(INT) are available
RW 0x00 11 GCONF
Attention – do not leave the outputs floating in tristate
condition, provide an external pull-up or set this bit 1.
4..6 Reserved, set to 0
7 test_mode
0: Normal operation
1: Enable analog test output on pin REFR2
TEST_SEL selects the function of REFR2:
0…4: T120, DAC1, VDDH1, DAC2, VDDH2
R+C 0x01 4 GSTAT
W 0x03 4 TEST_SEL
Attention: Not for user, set to 0 for normal operation!
8 shaft1
1: Inverse motor 1 direction
9 shaft2
1: Inverse motor 2 direction
10 lock_gconf
1: GCONF is locked against further write access.
Bit GSTAT – Global status flags
0 reset
1: Indicates that the IC has been reset since the last
read access to GSTAT.
1 drv_err1
1: Indicates, that driver 1 has been shut down due
to overtemperature or short circuit detection
since the last read access. Read DRV_STATUS1 for
details. The flag can only be reset when all error
conditions are cleared.
2 drv_err2
1: Indicates, that driver 2 has been shut down due
to overtemperature or short circuit detection
since the last read access. Read DRV_STATUS2 for
details. The flag can only be reset when all error
conditions are cleared.
3 uv_cp
1: Indicates an undervoltage on the charge pump.
The driver is disabled in this case.
Bit SLAVECONF
3..0 TEST_SEL:
selects the function of REFR2 in test mode:
0…4: T120, DAC1, VDDH1, DAC2, VDDH2
8
R 0x04 + INPUT
8
Attention: Not for user, set to 0 for normal operation!
Bit INPUT
0..6 Unused, ignore these bits
7 Reads the state of the DRV_ENN pin
31.. VERSION: 0x01=first version of the IC
24 Identical numbers mean full digital compatibility.
