bus address for the LTC5100 is 0x0A (hex). When the
MSB .. LSB. The register set and I 2 C command set for the
LTC5100 are documented in Table 7 through Table 30.
Read/Write bit that follows is a “1”, the resulting 8-bit word
becomes 0x15. When the Read/Write bit is a “0”, the 8-bit
word becomes 0x14. To communicate with the LTC5100,
the bus master transmits the LTC5100 address followed
by a command byte and data as defined by the I 2 C bus
specification and shown in Figure 28 and Table 4. Note that
16 bits of data are always transmitted, low byte first, high
byte last. Within each transmitted byte, the bit order is
