ADVSET3 (PROG)

Advanced Settings 3

Address:

110000

Type:

R/W

Description:

Advanced settings for interface 3

[4] STBIT_DC_CK_DIS1: Duty cycle check (DC>0.25) on start bits

0: duty cycle check enabled

1: duty cycle check disabled

[3] STBITERR_RST_CNT1: Manchester decoder Bit counter reset upon start bit error

0: start bit error does not reset the counter

1: start bit error resets the counter

[2:0] SYNC_DELAY_PSI1_PSI2: SYNC pulse time delay between PSI5 interface 1 and 2 in case of

automatic SYNC pulse generation

This bit takes effect only in case of automatic generation on both interfaces

000: no delay

001 - 111: 2µs/LSB

Default value:

010

000

R/W

[15] STG_MASK: Short to ground does not switch off channel

0: short to ground switches off the channel after filter time

1: short to ground does NOT switch off the channel

[14:11] FIXED_THR_SEL: Fixed threshold setting for PSI5 channel 2

Ibase + 5.5mA + (15-5.5)/16*bits[14:11]mA (1)

[10] RESERVED

[9] TRACKING_SEL:

0: Standard threshold tracking algorithm (default, recommended)

1: Fast tracking algorithm

[8:7] BLANKING_SEL: Blanking time selector at sensor startup:

00 : 128 µs

11: 128 µs

01: 5 ms

10: 10 ms
