25.1 RXBUFMOV
The RXBUFMOV instruction reads data from the RX FIFO and places the data at a specified memory
location as illustrated in Figure 35.
25.2 TXBUFCP
The TXBUFCP instruction copies a block of data starting at a specified memory location into the TX FIFO as
illustrated in Figure 35.
25.3 MEMCP
The MEMCP instruction copies a block of data starting at a specified memory location into another memory
location as illustrated in Figure 35.
25.4 MEMCPR
The MEMCPR instruction copies a block of data starting at a specified memory location into another
memory location while reversing the endianess. In other words the byte at memory location A+n is copied to
memory location E+C-1-n.
25.5 MEMXCP
The MEMXCP instruction xors two blocks of data and writes the result back to the memory location of the
second block. This is primarily used as a subroutine for some of the security instructions. It can also be used
to clear (set to zero) blocks of RAM with one short SPI instruction. By using the same source and target
address, the data is xor’ed with itself, which always results in zero being written back to the RAM.
