Flags ER: Mi, M+1,Su, and Su+1 are not BCD.

Indirectly addressed DM word is non-existent. (Content of DM word is

not BCD, or the DM area boundary has been exceeded.)

CY: ON when the result is negative, i.e., when Mi is less than Su.EQ: ON when the result is 0.The following example works much like that for single-word subtraction. In thisexample, however, BSET(71) is required to clear the content of DM 0000 andDM 0001 so that a negative result can be subtracted from 0 (inputting an 8-digitconstant is not possible).Example
