The PRU-ICSS supports a broadside interface, which uses the XFR (XIN, XOUT, or XCHG) instruction to transfer the contents of PRUn (where n = 0 or 1) registers to or from accelerators. This interface enables up to 31 registers (R0-R30, or 124 bytes) to be transferred in a single instruction. This section details the various accelerators that are available to the PRUn through the broadside interface.
Each of those functions have a unique XIN ID to determine which operation will occur. For more information see Table 7-32.
