Operation with Multiple Masters
If the MAX6958/MAX6959 are operated on a 2-wire
interface with multiple masters, a master reading the
MAX6958/MAX6959 should use a repeated start
between the write, which sets the MAX6958/MAX6959s
address pointer, and the read(s) that takes the data
from the location(s) set by the address pointer. It is
possible for master 2 to take over the bus after master
1 has set up the MAX6958/MAX6959s
address pointer
but before master 1 has read the data. If master 2 sub-
sequently changes the MAX6958/MAX6959s
address
pointer, then master 1's delayed read may be from an
unexpected location.
Command Address Autoincrementing
Address autoincrementing allows the MAX6958/
MAX6959 to be configured with the shortest number of
transmissions by minimizing the number of times the
command byte needs to be sent. The address pointer
stored in the MAX6958/MAX6959 increments after each
data byte is written or read, unless the address equals
01111111 (Table 3).
Digit Type Registers
The MAX6958/MAX6959 store display data in five regis-
ters. The four digit registers each control the seven
numeric segments of a seven-segment digit, but not
the DP segments. The segments register controls eight
individual LEDs, which can be any mix of discrete LEDs
and any or all of the DP segments of the four 7-seg-
ment digits (Table 5) (Figure 10).
