12. tpd2 is determined by the time it takes the internal digital PLL to reach a locked condition, which, in turn, is governed by the MCLKI/
XTALI frequency and the PLL output frequency. For a 135-MHz PLL output and an MCLKI value of 24.576 MHz, tpd2 is typically 25 s.
For an 11.264-MHz PLL output clock and a 1.024-MHz MCLKI/XTALI master clock, tpd2 is typically 360 s.
