Data)
Takes the logical AND of the byte data in the condition code register (CCR) and the
immediate data, and returns the results into the "CCR".

■ ANDCCR (And Condition Code Register and Immediate Data)

Assembler format: ANDCCR #u8
CCR and u8 → CCR
Operation:
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.
