Differences between "LDR r4, =0x50013ffc " and making the address 0x50013ffc using several instructions in thumb16- cortex M3

Hello, I wrote a program in assembly using thumb 16 instructions for ARM M3 (LPC1313FBD48), (I just want to use thumb16 instructions in the program). I need to change the value in address: 0x50003ffc...

ARM64: LDR (register) SXTX extend

Hi, What's the purpose of the SXTX extend? I understand the concept of sign extension when, say, the source register is 32-bit and the target is 64-bit. In this case, however, both registers are...
