55 / 100 page  ST6200C ST6201C ST6203C Doc ID 4563 Rev 5 55/100 INSTRUCTION SET (Cont’d) Conditional Branch. Branch instructions perform a branch in the program when the selected condi- tion is met. Bit Manipulation Instructions. These instruc- tions can handle any bit in Data space memory. One group either sets or clears. The other group (see Conditional Branch) performs the bit test branch operations. Control Instructions. Control instructions control microcontroller operations during program execu- tion. Jump and Call. These two instructions are used to perform long (12-bit) jumps or subroutine calls to any location in the whole program space. Table 17. Conditional Branch Instructions Notes : b 3-bit address rr Data space register e 5 bit signed displacement in the range -15 to +16 Δ Affected. The tested bit is shifted into carry. ee 8 bit signed displacement in the range -126 to +129 * Not Affected Table 18. Bit Manipulation Instructions Notes: b 3-bit address * Not Affected rr Data space register Bit Manipulation Instructions should not be used on Port Data Registers and any registers with read only and/or write only bits (see I/O port chapter) Table 19. Control Instructions Notes: 1. This instruction is deactivated and a WAIT is automatically executed instead of a STOP if the watchdog function is selected. Δ Affected *Not Affected Table 20.
