Read Global Configuration Register
(Command Code 0101)
The Read Global Configuration Register command,
0101, outputs the global configuration registers. The
address bits following this command are ignored.
When the MAX1253/MAX1254 receive a read global
configuration register command, they output 5 bytes of
data: 2 bytes from the channel enable register, 2 bytes
from the input configuration register, and 1 byte from
the setup register, all MSB first. See the Global
Configuration Registers section for more details.
RESET (Command Code 0111)
The RESET command, 0111, resets the device. This
command returns the MAX1253/MAX1254 to their
power-on reset state, placing the device into shutdown
mode. The address bits in the command are ignored.
See the Power-Up/Reset Defaults Summary section for
more details.
Clear Channel Alarm for Selected Channel
(Command Code 1000)
The Clear Channel Alarm command, 1000, clears the
alarm bits in the alarm register and resets the fault
counter for the addressed channel. See the Alarm
Register section for more details. See Table 3 for chan-
nel addresses.
Clear Alarm Register for All Channels
(Command Code 1001)
The Clear Alarm Register for All Channels command,
1001, clears the entire alarm register and resets the
fault counters for the internal TEMP sensor, the VDD
monitor, and the AIN0–AIN7 channels. The address bits
in the command are ignored. See the Alarm Register
section for more details.
Write Current Data Register for Selected
Channel (Command Code 1010)
The Write Current Data Register for Selected Channel
command, 1010, writes to the addressed channel’s cur-
rent data register. This command sets an initial condi-
tion when using the averaging filter option (see the
Averaging section). This command can also be used for
testing the thresholds, fault counters, and alarm func-
tions (Figure 8). See Table 3 for channel addresses.
Write Current Data Register for All
Channels (Command Code 1011)
The Write Current Data Register for All Channels com-
mand, 1011, writes to the current data registers of all
channels sequentially, starting with the internal temper-
ature sensor, then the VDD monitor, followed by chan-
nels AIN0 to AIN7. The address bits are ignored. Use
this command for testing and setting initial conditions
when using the averaging filter option (see the
Averaging section).
