TMS570LS0432: Warm Reset also set PORRST bit in SYSESR

Part Number: TMS570LS0432


Hello Support,

According to spnu569.pdf, Section

2.7      S2, System Reset Switch

Pressing S2 switch will produce WARM RESET which means Bit 3 [EXTRST] of SYSESR Register.

Before pressing S2 Switch, I have cleared SYSESR Register.

After pressing S2 switch, I see that EXTRST [Bit 3] as well as PORRST [Bit 15] are set within SYSESR register.

Can you please tell me what is the error with respect to specification of Warm Reset?

Thank you.

Regards

Pashan
