where:
cond
Rd
Rn
Rm
SDIV performs a signed integer division of the value in Rn by the value in Rm.
UDIV performs an unsigned integer division of the value in Rn by the value in Rm.
For both instructions, if the value in Rn is not divisible by the value in Rm, the result is rounded
towards zero.
Do not use SP and do not use PC
These instructions do not change the flags.
SDIV{cond} {Rd,} Rn, Rm
UDIV{cond} {Rd,} Rn, Rm
; Signed divide, R0 = R2/R4
; Unsigned divide, R8 = R8/R1
