APPLICATION NOTE

Programmer Board
Micronas

4.4.
Data Formats
The protocol between the programmer board and the Hall sensor defines fixed lengths
for the data, command, and address words to be transmitted:
– Command (CMD): 3 bit
– Address (ADR): 4 bit
– Data (DAT): 14 bit
– Command Parity (CP): 1 bit
– Address Parity (AP): 1 bit
– Data Parity (DP): 1 bit
Reminder: For communication with the programmer board, the 14 data bits are
encoded in four ASCII characters: DAT3, DAT2, DAT1, and DAT0.
As every register has a different length, not all of the 14 bits are used. Furthermore,
there is a difference between the write format (transfer board
 IC) and the read format
(transfer IC
 board). Table 4–6 shows which of the 14 bits are valid for each register
(write format and read format).
Table 4–6:
