ORCCR (Or Condition Code Register and Immediate Data)
Takes the logical OR of the byte data in the condition code register (CCR) and the
immediate data, and returns the results into the "CCR".
■
ORCCR (Or Condition Code Register and Immediate Data)
Assembler format:
ORCCR #u8
Operation:
CCR or u8
→
CCR
Flag change:
S, I, N, Z, V, and C: Varies according to results of calculation.
Execution cycles:
c cycle(s)
The number of execution cycles is normally "1". However, if the instruction immediately after
involves read or write access to memory address "R15", the system stack pointer (SSP) or the user
stack pointer (USP), then an interlock is applied and the value becomes 2 cycles.
