Bytes received after the command byte are data bytes.
The first data byte goes into the internal register of the
MAX6958/MAX6959 as selected by the command byte
(Figure 7).
The address pointer in the MAX6958/MAX6959 autoin-
crements after each data byte. If multiple data bytes
are transmitted before a STOP condition is detected,
these bytes are stored in subsequent MAX6958/
MAX6959 internal registers (Figure 8), unless the
address pointer has reached address 01111111. The
address pointer does not autoincrement once address
01111111 has been reached (Table 3).
Message Format for Reading
The MAX6958/MAX6959 are read using the 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 read using the same rules as for a write
(Table 3). A read is initiated by first configuring the
MAX6958/MAX6959s’ command byte with a write com-
mand (Figure 6). The master can now read n consecu-
tive bytes from the MAX6958/MAX6959. The master
acknowledges receipt of each read byte during the
acknowledge clock pulse. The master must acknowl-
edge all consecutive bytes received except the last
byte. The final read byte must be followed by a not
acknowledge from the master and then a stop condi-
tion (Figure 9). The first data byte is read from the reg-
ister addressed by the initialized command byte
(Figure 8). Reset the address pointer when performing
read-after-write verification because the stored byte
address is autoincremented after the write. The
address pointer does not autoincrement if it points to
register 01111111 (Table 3).
Table 4 is the register address map.
