TMS320F280025C: about PLL Reference Clock Lost Detection

Mag dai

Part Number: TMS320F280025C

In TMS320F28002x Technical Reference Manual (SPRUIN7A), it mention some registers as follows, but I cannot find them in CCS window or TRM 3.13 System Control Registers.

3.7.12.2 PLL Reference Clock Lost Detection

MCDCR.SYSREF_LOST_MCD_EN

MCDCR.SYSREF_LOSTS

SYPLLLSTS.REF_LOSTS

is this function relevant with 280025C?

PLUS:

I found the defination of MCDCR in this LAUNCHXL-F280025C: PLL Reference Clock Lost Detection - C2000 microcontrollers forum - C2000︎ microcontrollers - TI E2E support forums,

but what's SYPLLLSTS?

Hi Mag,

These bits have been updated internally in our documents but somehow have not made it yet in the public release. We are working with our documentation team for the updated version of SPRUIN7 F28002x TRM that will have these bit descriptions. In the meantime, for your reference please use the MCDCR bit descriptions in the link you referenced: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1011111/launchxl-f280025c-pll-reference-clock-lost-detection

For SYSPLLSTS.REF_LOSTS, this can be found in SYSPLLSTS register with description below:

Hi Mag,

For SYSPLLSTS.REF_LOSTS, this can be found in SYSPLLSTS register with description below:

Will also follow up with our software team on the availability of ClkCfgRegs (PLL registers) in CCS Registers window.

Best regards,

Joseph
