The MCM20027 is put into a standby mode via the I
2
C
interface by setting the
sby
bit of the
Power Configura-
tion Register
.
Additional control of the MCM20027 can be had using
the Reset Control Register;
Reset Control Register; Ta-
ble 20
.
Setting the
sir
bit of this register will reset all the non
programmable Sensor interface registers to a known re-
set state.
Setting the
par
bit of this register will reset all the Sen-
sors non programmable Post ADC registers to a known
reset state.
Setting the
asp
bit of this register will reset all the sen-
sors registers in the ASP processing chain to a known
reset state.
Setting the
ssr
bit of this register will reset all the non-
user programmable registers to a known reset state.
This is useful in situations when control of the
MCM20027 has been lost due to system interrupts and
the device needs only to be restarted using the earlier
user programmed values.
Setting the
sit
bit allows the user to completely reset the
MCM20027 to the default state via the serial control In-
terface. For both reset bits,
ssr
and
sit
, the user must
return those bits to 0 to enable continued operation
