7. Operation Mode 3

HAL856

This operation mode is set by sending the “j3” command.

Note: The HAL856 is a two-wire device. It is programmed by modulating the supply

voltage, and it responds by modulating its current consumption. In order to

detect the current levels of the sensor, the Hall Programmer Board V 5.1 mea-

sures the sensor’s supply current. Hence, only one HAL856 can be connected

to the board.

Communication:

prog. board

Section 7.1 and Section 7.2 contain a detailed description of communication between

the PC and the programmer board V 5.1. Particularly, all board commands available in

the operation mode “j3” are listed.

Communication:

prog. board

sensor

The communication between the programmer board and the Hall sensor is described in

Section 7.3

Data formats

The data formats for communication between both the PC and the board, and the

board and the sensor are summarized in Section 7.4

Programming

procedure

Finally, Section 7.5 depicts the programming procedure and gives an example of a

complete programming sequence.
