PCC_15 CLK_APB_PCC (4) Internal MCLK PCC Module Clock — — fAPBn MHz
Note:
  1. PCC ISIZE = 0 (8-bits). DMA descriptors used for continuous data acquisition, with highest priority for the DMA on the AHB bus (DMA.CTRLB.QOSx=2). fAPBn running at Max frequency (PCC_15).
  2. PCC_DENBSETUP ≥ PCC_7.
  3. PCC_DENBHOLD ≥ PCC_9.
  4. CLK_APB_PCC_ ≥ (2 * PCC__CLK).
