R5-R6 - Unused Registers
Address 0x5, 0x6
Type R/W
Reset Default 8h’00
Bit
7:00
Field Name
Unused
Description or Comment
Write transactions to this register are ignored. Read transactions will
return a “No Response Frame.” A no response frame contains all
zeros (see PWI 1.0 specification).
R7 – VO2 Voltage Register (I/O Voltage)
Address 0x7
Type R/W
Reset Default 8h’78
Bit
7
Field Name
Sign
Description or Comment
This bit is fixed to ‘0’. Reading this bit will result in a ‘0’. Any data written into
this bit position using the Register Write command is ignored.
Fixed voltage value. A code of all ones indicates maximum voltage while a code
of all zero indicates minimum voltage. Default value is in bold.
