PORF

Power-On Reset flag bit. The bit is reset by writing

‘0’ to this bit.

No detection

Detection

EXTRF

External Reset (RESETB) flag bit. The bit is reset by writing

‘0’ to this bit

or by Power-On Reset.

No detection

WDTRF

Watch Dog Reset flag bit. The bit is reset by writing

‘0’ to this bit or by

Power-On Reset.

No detection

OCDRF

On-

chip debugger reset flag bit. The bit reset by writing ‘0’ to this bit or by

Power-On Reset

No detection

BODRF

Brown-Out Reset & Interrupt flag bit. The bit is reset by writing

‘0’ to this

bit or by Power-on Reset or by BOD acknowledge signal.

No detection

Detection

NOTES

When the Power-on Reset occurs, the PORF and BODRF bits are only set to

“1”,

the other flag (WDTRF) bits are all cleared to

“0”.

When the Power-on Reset occurs, the EXTRF bit is unknown, at that time, the
EXTRF bit can be set to

“1” when the external Reset (RESETB) occurs.

When a reset except the POR occurs, the corresponding flag bit is only set to

“1”,

the other flag bits are kept in the previous values.
