LDC B/W
Moves the source operand contents to the condition code register. The
condition code register size is one byte, but in transfer from memory, data is
read by word access.
CCR → (EAd)
STC B/W
Transfers the CCR contents to a destination location. The condition code
register size is one byte, but in transfer to memory, data is written by word
access.
CCR ∧ #IMM → CCR
ANDC B
Logically ANDs the condition code register with immediate data.
CCR ∨ #IMM → CCR
ORC B
Logically ORs the condition code register with immediate data.
CCR ⊕ #IMM → CCR
XORC B
Logically exclusive-ORs the condition code register with immediate data.
PC + 2 → PC
NOP —
Only increments the program counter.
Note: * Size refers to the operand size.
