PSNID(1)

PSNID(0)

Frames 3 through (n – 1) (where n = 5 to 11)

PSNID[1:0]

Bits 7-6

Position ID of device on UART bus. Each device process information for one sensor. Four sensors can be

sensed on the UART bus. Position settings are defined in the EEPROM map.

Position 0

Position 1

Position 2

Position 3

Bit 5

Not used. Set to 0.

Bits 4-0

Top five bits of bank or field data. See Table 3 and Table 4 for valid addresses and types of data.

Frame n (where n = 4 to 11)

PSNID[1:0]

Bits 7-6

Position ID of device on UART bus. Each device process information for one sensor. Four sensors can be

sensed on the UART bus. Position settings are defined in the EEPROM map.

Position 0

Position 1

Position 2

Position 3

Bit 5

Not used. Set to 0.

Bits 4-0

Next or last five bits of bank or field data. See Table 3 and Table 4 for valid addresses and types of data. Data

length for each calibration write frame is 5 bits. Maximum number of frames that can be written from one

command is nine; therefore, maximum data length is 44 bits.
