Dear Sir

 

I want to ask about the pin assignment.

 

I refer to IMX6ULLRM Rev. 1, 11/2017.

It is described at P4099 Table 60-1. XTALOSC External Signals.

I think that XTALOSC_REF_CLK_32K can be assigned to GPIO1_IO03(ALT3).

 

On the other hand, it seems that we cannot select ALT3 with SW_MUX_CTL[MUX_MODE].

P1571 32.6.10 SW_MUX_CTL_PAD_GPIO1_IO03 SW MUX Control

 

Q1.

How can I allocate XTALOSC_REF_CLK_32K to GPIO1_IO03?

 

Best Regards,

Eishi SHIBUSAWA
