F500 UINT16 PACKED BITFIELD
First register indicates I/O state with bits 0(MSB)-15(LSB) corresponding to I/0 state 1-16.
Second register indicates I/O state with bits 0-15 corresponding to I/0 state 17-32 (if
required). Third register indicates I/O state with bits 0-15 corresponding to I/0 state 33-48
(if required). Fourth register indicates I/O state with bits 0-15 corresponding to I/0 state
49-64 (if required). The number of registers required is determined by the specific data
item.
A bit value of 0 = Off, 1 = On
