Refering to the chart below can we can program any interrupt source in the interrupt channels?For instance, can we program INT_REQ0 as DCAN interrupt source ?
Is there any table of all interrupt sources that can be referenced? None could be found in the RM48 user guide.
Regarding the power management is there any power up sequence to follow ? The graph below with the timing chart, It appears that the VCCIO comes before Vcc power on, is that correct?
Flavio,
On the RM48 (as well as all Hercules Safety Microcontroller) the CHAN0 and CHAN1 are hardwired to INT_REQ0 and INT_REQ1 so they cannot be remapped.
All other CHANx, are after reset by default mapped to there corresponding INT_REQx and can be remapped at will.
These information is visible in the RM48 Datasheet (page 93 section 4.15.2 Interrupt Request Assignments) and TRM (page 502 Figure 15-4 and 15-5)
Concerning your second question, where did you find this timing diagram?
Here is what is stated in the RM48 Datasheet on page 54:
Please let me know if I've answered your questions.
