MSPM0G1506: Workaround for VREF_ERR_01

Tool/software:

Hello

Regarding the Workaround for VREF_ERR_01, what specific modifications are required?
I'm thinking of using delay_cycles to wait for 200us, but is this close enough?
Do you have any sample code?

Thank you

Hi Kei,

You can use delay_cycles to add in the necessary delay. Another option is to use a timer set to 200us and set a boolean flag to know when you're VREF has settled.

Luke

Thank you for your reply.

When using delay_cycles, how do I calculate the number of cycles to wait for 200us?

Thank you very much.

Hi Kei,

A delay cycle should be equal to 1 clock cycle, so the equation would be DelayCyclesVal = DelayTime(s) * CPUFrequency (Hz).

For 200us and at 32MHz it will be DelayCyclesVal = 200 * 10^-6 * 32000000 = 6400.

Luke
