MVSS
Power supply pins for
controller block
Power supply pins for the controller block.
Normally, VDD = 3.0 to 3.6 V.
When only the CPU operates (when the
75-kHz/32.768-kHz oscillator is used), it can
operate at
VDD = 1.8 to 3.6 V.
In the backup state (when the CKSTP
instruction is executed), current dissipation
decreases (10
mA or below), allowing the power
supply voltage to be reduced to 1.0 V.
Raising the voltage on MVDD pin from 0 V to
1.8 V or higher triggers a system reset, causing
the program to start from address 0 (power-on
reset).
(Note) At power-on reset operation, allow 1 ms
to 50 ms while the device power supply
voltage rises.
(Note) The backup current is the total of
currents for CVDD, MVDD and DVDD.
17
PDO
Output pin for a phase error signal between the
EFM and PLCK signals.
Drives one of four values: AVDD, Hi-Z,
VREF, AVSS
18

TMAX detection result output pin.
Longer than specified cycle: Drives a high
level (AVDD)
Shorter than specified cycle: Drives a low
level (AVSS)
Within specified cycle: Hi-Z
