Instruction Set Architecture—IP2022 User’s Manual 106 www.ubicom.com Example: add     0x099,w This  example  adds  the  contents  of  W  to  data
memory location 0x099. For example, if the data
memory location holds 0x7F and W holds 0x02,
this  instruction  adds  0x02  to  0x7F,  writes  the
result  0x81  into  the  data  memory  location,  and
clears the C and Z bits. It sets the DC bit because
of the carry from bit 3 to bit 4.
