• Why ARM32-bit commands in Cortex disassembly?
    As I understand the STM32F4 programming manual (DM00046982), or the Cortex M4 TechRefManual, a Cortex M4 processor as the STM32F4 can only work with Thumb mode (T2 I think). But if I use the ST4Discovery...
  • FRAME ADDRESS and "fp"
    I inherited some ARM assembly code for an NXP LPC microcontroller, and came across something I can't find out much about. Specifically, in an ISR coded in assembly, something called 'fp' is pushed and...
  • Max. Ethernet Frame Size
    I have board MCB2300 (with LPC 2378 microprocessor). I read in LPC23xx User manual that MAXIMUM FRAME LENGTH (MAXF)sets to the value 0x0600, which represents a maximum receive frame of 1536 octets...
  • Remote frame broadcast
    when we send message to node that node will give response either positive or negative but when we send Remote frame to node that node will send the response for the remote frame or it will ignore it...
