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 for-
mat (transfer IC
 Board). Table 6–6 shows which of the 14 bits are valid for each reg-
ister (write format and read format).
