A typical application may sample the MAX110 at regu-
lar intervals, keeping the MAX110 shut down between
samples. This type of usage can be evaluated by using
the “P” command in the Shutdown Power Cycling
screen. The power-cycling loop repeatedly puts the
MAX110 into sleep mode for a user-specified length of
time, wakes up the MAX110, takes a reading, and
powers the MAX110 down again. The “P” command
runs continuously, until halted by either the “U” or “D”
command.
The parameters that pertain to the “P” command are as
follows: the state of the PD and PDX bits before and
after shutdown, the sleep time, and the optional NOOP,
AUTO NULL, and GAIN CAL cycles.
The sampling rate is determined by setting the sleep
time, which is the length of time the program keeps the
MAX110 in shutdown mode. The program allows a
maximum sleep time of 65 seconds.
If the internal RC oscillator is used, activating the PDX
bit may cause the BUSY line to remain low. This condi-
tion should be cleared by starting the power-up
sequence with a configuration word whose MSB is 0 (a
NOOP cycle). If an external oscillator is used, the PDX
bit has no effect and the NOOP cycle is not required.
Supply current will not be as low as in the internal RC
oscillator mode, unless the external oscillator is halted
during shutdown.
The PDX power-down bit has no effect unless the
internal RC oscillator is being used. Normally, the PD
and PDX bits should be set to 1 in shutdown mode, and
both should be 0 in active mode.

should settle at less than 1mA. There will be short
current spikes whenever a command is sent to the
MAX110.

Jumper J9 can be used to measure the supply current
drawn by the MAX110 IC. To measure the supply current,
use the following procedure:

To restore the MAX110 EV kit, use the following
procedure:
1) Turn off the MAX110 EV kit power.
2) Disconnect the current meter.

current can be measured in a similar way. Remove the
shunt from J4 1-2 and connect a current meter. Current
will flow from J4 pin 2 to J4 pin 1. Or, the current meter
may be connected between the V
-5V edge pad. Current will flow from the V
to the -5V edge pad.
When starting the MAX110 program from the DOS
prompt, several command-line options are available.
For a list of available options, run MAX110 with the “?”
command-line option. Refer to Table 3.
When the MAX110 program begins operation, it is in its
Opening screen. Use the space bar to select the serial
communications port to which you have connected the
80C32 module. Press the ENTER key to advance to the
Terminal screen.
The MAX110 program displays its Terminal screen
when it is establishing communications with the 80C32
module. When power is applied to the 80C32 module
or reset is pressed, banner message identifying the
80C32 module is displayed. After the module com-
pletes its self check, it says that all tests have passed.
At this point, use the ALT+L command to load the RAM
resident program into the 80C32 module. After the RAM
resident program has been loaded, use the ALT+C
command to advance to the Control Panel screen.
