48 MHz Output Specifications
Software may configure GPIO<11> or GPIO<12> alternate functions to enable the 48-MHz clock
output. The 48-MHz output clock is a divided-down output generated from the 312-MHz
peripheral PLL. Refer to Table 5-15 for the 48-MHz output specifications. Refer to Section 3 of
this document for GPIO alternate functions in the pin usage table.
