Add the following informational bullet:
Consider a situation where the DSP is doing an external memory read from a FIFO. If an interrupt occurs during a read access to external memory, the read may be aborted. The program control jumps into the interrupt service routine (ISR). In that case, the processor will re-issue the same read after returning from the interrupt. While this is not an issue for static memories, it will cause a loss of synchronization with, for instance, FIFO devices. If operation with a FIFO is required, make sure that the read accesses cannot be interrupted.

In point # 1, it is mentioned as:
Maximum Core Speed puts the peripheral: core clock ratio at HCLK = 1/2 CCLK and puts the core clock at CCLK= 1600 MHz.

Change to: CCLK= 160 MHz.

Replace the following paragraph:
If the—No Boot on Software Reset—Run mode (RMODE) bit of the Next System Configuration Register has been set to 0, following a soft reset, program flow jumps to address 0xFF0000 and begins executing the boot ROM code at that location to reboot the DSP. A software reset can also be used to reset the boot mode without doing an actual reboot. If bit 4 of the Next System Configuration Register has been set to 1, following a soft reset, program flow jumps to address 0x000000 and completes reset without rebooting the DSP.
With the following paragraph:
Following a soft reset, program flow jumps to address 0xFF0000 and begins executing the boot ROM code at that location to reboot the DSP.

It would be useful to add diagram with the register bits definition, reset value and the I/O address for the CANRML register. The new figure for the CANRML register would be ideltical to figure 21-20. Each bit would be defined as RMLn. The reset value for this register would be 0x0000 and the I/O address would be 0x10-0x00E.

1 = disabled

Change to:
0 = disabled
