Note that there are no simple rules for ARM.
Some ARM chips may have individual interrupt vectors for receive, transmit and error. It's just a question of what work the manufacturer have done when selecting or designing the "microcontroller" features that they glue to the core. |

[ARM] Default state of interrupts | 01/01/70 00:00 | |
Normally vectorized interrupt controller | 01/01/70 00:00 | |
but isn't this the case with ALL microcontrollers? | 01/01/70 00:00 | |
Often three layers of enable | 01/01/70 00:00 | |
This is the case here (LPC17xx)... | 01/01/70 00:00 | |
May vary a lot | 01/01/70 00:00 | |
Not the case anymore for Cortex-M3s. | 01/01/70 00:00 | |
Startup code? | 01/01/70 00:00 | |
not startup code, but the after-reset state | 01/01/70 00:00 | |
Hw-acceleration | 01/01/70 00:00 | |
According to the datasheet of my CM3 ... | 01/01/70 00:00 | |
