The MAX6618 is read using the MAX6618’s internally
stored command byte as an address pointer the same
way the stored command byte is used as an address
pointer for a write. The pointer autoincrements after
each data byte is read. Thus, a read is initiated by first

THE RESULT CONSISTS OF RESLO FOR THE 8 LEAST SIGNIFICANT BITS (LSBS) AND RESHI FOR THE 8 MOST SIGNIFICANT BITS (MSBS), RESULTING IN A 16-BIT WORD.
TEMPERATURE DATA AND ERROR CODES ARE GIVEN AS 16-BIT WORDS.

configuring the MAX6618’s command byte by perform-
ing a write. The master can now read N consecutive
bytes from the MAX6618 with the first data byte being
read from the register addressed by the initialized com-
mand byte (Figure 10).
