BUG

[Tan Seng Yaw]

Dear Sir/Madam,

A bug has been found on LDC instruction.
Please refer to line 19 below, the translated instruction format should be 
01406910 but not 01406900, because the register is ER1 not ER0.

  15                    start:
  16 00f4 7A010000              mov.l   #data,er1
  16      0000
  17 00fa F855                  mov.b   #0x55,r0l
  18 00fc 6898                  mov.b   r0l,@er1
  19 00fe 01406900              ldc.w   @er1,ccr
  20                    
  21 0102 38C0                  mov.b   r0l,@0xc0:8
  22 0104 38C1                  mov.b   r0l,@0xc1:8
  23                    
  24                            .bss    data,4
  25                            .end
