Microprocessor Interface
Overview
The microprocessor interface can be in serial mode or in parallel mode. When the external signal SPIEN is cleared to 0, the interface is in parallel
mode, and when SPIEN signal is set to 1, the interface is in serial mode.
The parallel microprocessor interface can be connected directly to a suitable processor or to a FPGA as shown in Figure 31 Microprocessor
. The interface has 8 bits data bus and 6 bits address bus. The interface has also write, read, chip select and inter-
rupt signals. In addition there is a mode signal: MPM. When MPM signal is set to 1, the interface is in Intel mode, and when MPM signal is cleared to
0, the interface is in Motorola mode.
.
Figure 31 Microprocessor Interface - Parallel Mode
The serial microprocessor interface can be connected directly to a suitable processor or to a FPGA. The interface has data, chip select and clock
signals.The microprocessor interface timing is based on the main clock domain. One microprocessor interface cycle is four main clock cycles.
Embedded Processor Download
The embedded processor has 2 mailboxes, I_FIFO and O_FIFO each of which has a 32 byte FIFO. Mailbox I_FIFO is used for firmware download
from the host to the embedded processor. Refer to page 90 and page 92 for registers related to the mailbox FIFOs.
The embedded processor is first checked to see if it is ready for download. This is done by reading direct register 0x16. If the result is 0x1, then
further downloading steps take place as indicated in the flowchart below.
The download should take place in the little endian format. If the download file is in big endian format and since the downloading takes place in 16
bit words, the lower byte should be swapped with the upper byte.
