15.3.2.1.3 5-Bit PODR_x Registers
The 5-bit PODR_x registers are the output data registers for PPCIBGn (PODR_PCIBG) and PPCIBRn
(PODR_PCIBR). Figure 15-4 displays the 5-bit PODR_x registers.
15.3.2.1.4 4-Bit PODR_x Registers
The 4-bit PODR_x registers are the output data registers for PDMAn (PODR_DMA) and PFECI2Cn
(PODR_FECI2C). Figure 15-3 displays the 4-bit PODR_x registers.
