DIVXU
DIVXU (DIVide eXtend as Unsigned)
2. Programming solution for DIVXU.W R0, ER1
Example 1: Divide upper 16 bits and lower 16 bits of 32-bit dividend separately and obtain 32-bit
quotient
ZERODIV:
The resulting operation is 32 bits ÷ 16 bits
overflow occurs. The 32-bit quotient is stored in ER2, the 16-bit remainder in E1.

Dividend
Quotient
R0 = 0? (Zero divisor?)
Branch to ZERODIV if R0 = 0
Copy upper 16 bits of dividend to R2 and
zero-extend to 32 bits
Divide upper 16 bits of dividend
E2
Divide lower 16 bits of dividend (including repeated
division of upper 16 bits)
Store upper part of quotient in E2
Store lower part of quotient in R2
