GCR1 (PROG)

General Configuration Register 1

Address:

000001

Type:

R/W

Description:

Default value:

000

R/W

[15] PAR: Register parity

Odd parity bit for register bits [15:0]

[14] DIS_ADD_MUX: SPI address multiplexing disable

0: address multiplexing enabled

1: address multiplexing disabled

[13] PSI2_EXT_UDB: SYNC pulse generation for PSI5 interface 2

0: the trigger on SYNC2 pin or the SPI command determine the SYNC pulse length

1: the contents of UDB2 determine the SYNC pulse length (always true if timer enabled

bit[12:11]=10)

[12:11] PSI2_TRIG_SEL: SYNC pulse trigger source for PSI5 interface 2

00: SYNC pulse generated by SYNC2 pin

11: SYNC pulse generated by SYNC2 pin

01: SYNC pulse generated by SPI command

10: automatic SYNC pulse generation

[10] PSI2_TGAP_PW: SYNC pulse method for PSI5 interface 2

This bit takes effect only in case bit [13] = 1

0: tooth gap method

1: pulse width method

[9] PSI1_EXT_UDB: SYNC pulse generation for PSI5 interface 1



0: the trigger on SYNC1 pin or the SPI command determine the SYNC pulse length

1: the contents of UDB1 determine the SYNC pulse length(always true if timer enabled

bit[8:7]=11)

[8:7] PSI1_TRIG_SEL: SYNC pulse trigger source for PSI5 interface 1



00: SYNC pulse generated by SYNC1 pin

11: SYNC pulse generated by SYNC1 pin

01: SYNC pulse generated by SPI command

10: automatic SYNC pulse generation
