9.2.2 CLKO Output Clock Generation
This clock output is derived from MCLK based upon the setting of the CLKOSEL[2:0] bits in the
register.The reference for the PLL is not the input clock on MCLK, but the scaled version of MCLK (1.544MHz or
2.048MHz). The LTRCR.T1J1E1S bit also selects the proper PLL for use in generating the appropriate frequency.
This clock output pin is provided as an additional feature to eliminate the need for another board oscillator.
