CONTROL REGISTERS
When writing to a control register, the format shown in Table 16
must be used. See Table 9 for information on the configuration
of Bit D23 to Bit D16. The control registers are addressed by
setting the DREG[2:0] bits to 111 and then setting the
CREG[2:0] bits to the appropriate decode address for that
register, according to Table 17. These CREG bits select among
the various control registers.
Main Control Register
The main control register options are shown in Table 18 and
Table 19. See the Device Features section for more information
on the features controlled by the main control register.

Bit
Description
POC
The POC bit determines the state of the voltage output channels during normal operation. Its default value is 0.
POC = 0. The output goes to the value set by the POC hardware pin when the voltage output is not enabled (default).
POC = 1. The output goes to the opposite value of the POC hardware pin if the voltage output is not enabled.
STATREAD
Enable status readback during a write. See the Device Features section.
STATREAD = 1, enable.
STATREAD = 0, disable (default).
EWD
Enable watchdog timer. See the Device Features section for more information.
EWD = 1, enable watchdog.
EWD = 0, disable watchdog (default).
WD1, WD0
Timeout select bits. Used to select the timeout period for the watchdog timer.

ShtCctLim
Programmable short-circuit limit on the VOUT_x pin in the event of a short-circuit condition.
0 = 16 mA (default).
1 = 8 mA.
OUTEN_ALL
Enables the output on all four DACs simultaneously.
Do not use the OUTEN_ALL bit when using the OUTEN bit in the DAC control register.
DCDC_All
When set, powers up the dc-to-dc converter on all four channels simultaneously.
To power down the dc-to-dc converters, all channel outputs must first be disabled.
Do not use the DCDC_All bit when using the DC_DC bit in the DAC control register.
