29 LLD circuit
29.1
General Description
LLD circuit monitors Power supply Voltage level. When Power supply Voltage falls than the thresholdvoltage,
LLD reset this LSI.
29.1.1 Features
•
Judgement Voltage
:
1.8V
±
0.2V
•
generate LSI reset
•
Selectable LLD enable/disable
29.2
Description of resister
Control LLD validation by resister setting.
LLD is invalidated initially.
LLD can be validated by setting block control resister 45(BLKCON45) DLLD bit to “0”.
29.3
Description of operation
LLD circuit is controlled by DLLD bit of block control register 45(BLKCON45).
This circuit compares the power supply voltage with the threshold voltage. If the power supply voltage is below
the threshold voltage, LLD generate reset.
See DC characteristics(LLD) of AppendixC Electrical Characteristics for details about the threshold voltage.
