Sets IOUT Warning 2 limit to OC or UC.
Sets severe OC trip threshold.
Sets severe OC filter time.
200 ns.
900 ns. Default.
Description
Returns the peak input power since the register was last cleared.
Description
Always reads as 0x03, the number of data bytes that the block
read command should expect to read.
This is the result of the VIN × IOUT calculation that has not been
truncated. Byte 3 is the high byte, Byte 2 is the middle byte, and
Byte 1 is the low byte.
Description
Always reads as 0x08, the number of data bytes that the block
read command should expect to read.
This is the 24-bit energy accumulator in direct format. Byte 3 is
the high byte, Byte 2 is the middle byte, and Byte 1 is the low
byte.
Number of times that the energy count has rolled over, from
0x7FFF to 0x0000. This is a straight 16-bit binary value. Byte 5 is
the high byte, Byte 4 is the low byte.
This is the total number of PIN samples acquired and
accumulated in the energy count accumulator. Byte 8 is the high
byte, Byte 7 is the middle byte, and Byte 6 is the low byte.
