Using Arithmetic Status Bits
C always reset
V set if the BCD result is larger than 9999. Overflow results in a minor
error.
Z set if the destination value is zero
S set if the source word is negative; otherwise reset
Math Register (When Used)
Contains the 5–digit BCD result of the conversion. This result is valid at
overflow.
Example 1 (SLC 5/02 Processors Only)
The integer value 9760 stored at N7:3 is converted to BCD and the BCD
equivalent is stored in N10:0. The maximum BCD value possible is 9999.
Destination is displayed as
–26784, decimal
(equivalent to 9760 BCD).
