programming instructions

The programming word is set through a 10 bit shift

register via the data, clock and enable lines. The

data is entered in order with the most significant bit

(MSB) first and the least significant bit (LSB) last. The

enable line must be low for the duration of the data

entry, then set high to latch the shift register. The

rising edge of the clock pulse shifts each data value

into the register.

Notes:

(1) Refer to Application Information section for Current and Gain bit settings.

(2) Data bit 0 should always be set to “1”.

(3) Data bit 1 is reserved for future use, and should be set to “0”.
