in page 3293 in the reference manual of the i.MX RT1060 Processor Reference Manual, Rev. 4, 01/2026 is says,
"To select XBAR_IN03 to connect with XBAR_OUT07, according to the index of
XBAR_OUT07, select the SEL07 (same number with the selected XBAR_OUT index)
fields in the MSBs of the Select Register 3 XBAR_SEL3, and assign the index (0x03,
Hexadecimal) of the selected XBAR_IN in it.
XBAR_SEL3 &= 0x0011; /*Clear the SEL7 fields
XBAR_SEL3 |= 0x0300; /*Assign the 0x03 to the SEL7 fields "
so is it SEL07 or XBAR_SEL3? or is the MSBs of the reg. XBAR_SEL3 is called SEL07? and if this is true, how to use and where (SEL07) instead of the reg. address.
also is "XBAR_SEL3 &= 0x0011; /*Clear the SEL7 fields
XBAR_SEL3 |= 0x0300; /*Assign the 0x03 to the SEL7 fields" correct
thank you
