28 / 39 page  28 7010AS–DSP–07/07 AT572D940HF Preliminary 5.11.2 Peripheral Multiplexing The D940HF features three PIO controllers, PIOA, PIOB and PIOC, that multiplex the I/O lines of the peripheral set. Each PIO controller manages up to thirty-two lines. Each line can be assigned to one of the two peripheral functions, A or B. Table 5-6 to Table 5-8 define how the I/O lines of the peripherals A and B are multiplexed on the PIO Controllers. Note that some output only peripheral functions might be duplicated within the tables and are indicated with the suffix II and III. 29 30 31 Table 5-5.
