AWRL1432: How to set OSC_CLK_OUT pin to clock output

Allen35065

Part Number: AWRL1432

Tool/software:

Hi expert,

Customer want to use OSC_CLK_OUT (A7) pin to output clock signal on AWRL1432. But we don't find any registers in documents or SDK.

Please suggest how to use it.

Thank you.

Allen

Hey Allen,

I will need to look into this internally. Please give me a day or two.

Thank you for your patience,

Kristien

The question is asked by me, and my project want to use OSC_CLK_OUT (A7) as 40MHz clock signal output, when we I gave the AWRL1432 a 40MHz passive crystal.

Hey Liu,

You can use the following code to bring out the 40 MHz clock on pin A7:

volatile uint32_t * ANA_CFG_CLK_CTRL_REG1_CLKTOP = (volatile uint32_t *)0x50020004U;
*ANA_CFG_CLK_CTRL_REG1_CLKTOP |= (0x0C1U << 21);

Kristien
