where:
condis an optional condition code.
RdLo,RdHiare the destination registers for the 64-bit result. They also hold the two 32-bit accumulate operands.
RdLoRdHiRn, Rmare the registers holding the multiply operands.
The UMAAL instruction multiplies the 32-bit values
in RnRmRdHiRdLoRdLo, RdHi
You cannot use PC for any register.
You can use SP in ARM instructions but these are deprecated in ARMv6T2 and above. You cannot use SP in Thumb instructions.
This ARM instruction is available in ARMv6 and above.
These 32-bit Thumb instructions are available in ARMv6T2 and above. For the ARMv7-M architecture, they are only available in an ARMv7E-M implementation.
There is no 16-bit Thumb version of this instruction.
