TMS570LS1224: VRCTL register

Michal Timm

Part Number: TMS570LS1224
Other Parts Discussed in Thread: HALCOGEN, , TMS470MF06607

Where can I find VRCTL register description? In TRM (in the place where I should find it) there is a gap.
Below you will see comparisson between file generated in HalCoGen and TRM.

Hello,

This register is not implemented. It could be marked as reserved.
See this thread for explanation: e2e.ti.com/.../482907

Best regards,

Thank you,

In the example that I have get from QJ Wang there is VRCTL configuration (going into low power mode).
I am confused. What is the function of this reg?

    /** - Setup GCLK, HCLK and VCLK clock source for normal operation, power down mode and after wakeup */
    systemREG1->GHVSRC = (uint32)((uint32)SYS_OSC << 24U)
                       | (uint32)((uint32)SYS_OSC << 16U)
                       | (uint32)((uint32)SYS_PLL1 << 0U);

    /* Enable low-power modes */
    systemREG1->VRCTL = 0x0F;

    /* turn off all clock sources except main oscillator */
    systemREG1->CSDISSET = 0xFE;

Hello,
What is the MCU for which the code (example) was written?

See this thread: e2e.ti.com/.../743437
QJ Wang was trying to help me. During conversation, I sent my code to him and he resent this code to me in a private message. So this code was not posted on the forum.

But during searching information about low-power mode I found this thread:
e2e.ti.com/.../1353599
Sunil suggest that the VRCTL register needs to be configured to 0x0F...

Hello,
The second thread is for TMS470MF06607 where this register is described.
Let me check this.

Best regards,

Hi Timm,

As I said in private message, this register is reserved in TMS570 devices.
