TMS570LS3137: TMS570LS3137 : pbistSelfCheck() PBIST Activate/Clock Enable Register (PACT) configuration

Hello,

We use HALCOGEN version 4.7 to generate code for TMS570LS3137. The generated code has below instruction which is writing to reserved field of PBIST Activate/Clock Enable Register (PACT).

pbistREG->PACT = 0x3U;

Is it required to write to reserved field of PBIST module PACT register? As the TRM SPNU499C mentions that BIT-0 is the one used to enable PBIST internal clocks?

Thanks,

Kalyan
