ARM CortexM4 Introduction ARM CortexM processors are used in microcontrollers family of ARM microcontrollers It consists of 32bit processor cores The size of processor in terms of bits defines the maximum addressable range or the maximum address range it can handle For example, ARM CortexM4 microcontrollers can handle 2^32 = 4GB of memory address space. The ARM CortexM4 TM4C123 provides a 16bytes FIFO buffer to store data for transmission and another 16bytes FIFO buffer to save all received data When FEN is enabled, we can write up 16bytes of data block into the transmission FIFO buffer and let it transfer a byte a time. The CortexM4 NOP as described is not necessarily time consuming You could replace it to, say and reg, reg, or something coarsely equivalent to a nop in the context Alternatively, when toggling GPIO, you could also repeat the I/O instructions themselves to enforce the minimal length of a state (such as if your GPIO writing instruction takes at least 5ns, repeat it five times to get at least 25ns).
