Word 1
Bits 00-01
Current outputs only – When set (1), the wire on the output is broken or the
load resistance is too high. Bit 00 corresponds to channel 0, bit 01
corresponds to channel 2, and so on.
Bits 02-14
(02-16)
Not used – set to 0
Bit 15 (17)
Power Up bit. - This bit is set to 1 when all bits in the configuration
register (write word 5) are 0 (unconfigured state). The configuration
register can be cleared by either a reset, or by the user writing all zeroes to it.
