90E32
POLY-PHASE HIGH-PERFORMANCE WIDE-SPAN ENERGY METERING IC
Function Description

3.6.2
IDLE MODE (I MODE)
In Idle mode, all functions are shut off.
The analog blocks' power supply is powered but circuits are set into
power-down mode, i.e, power supply applied but all current paths are
shut off. There is very low current since only very low device leakage
could exist in this mode.
The digital I/Os' supply is powered.
In I/O and analog interface, the input signals from digital core (which
is not powered) will be set to known state as described in Table-3. The
PM1 and PM0 pins which are controlled by external MCU are active and
can configure the 90E32 to other modes.
Figure-7 Block Diagram in Idle Mode
Please note that since the digital I/O is not shut off, the I/O circuit is
active in the Idle mode. The application shall make sure that valid logic
levels are applied to the I/O.
Table-3 lists digital I/O and power pins’ states in Idle mode. It lists the
requirements for inputs and the output level for output.
