instructions
LDC B/W (EAs) → CCR, (EAs) → EXR
Moves the source operand contents or immediate data
to CCR or EXR. Although CCR and EXR are 8-bit
registers, word-size transfers are performed between
them and memory. The upper 8 bits are valid.
STC B/W CCR → (EAd), EXR → (EAd)
Transfers CCR or EXR contents to a general register or
memory. Although CCR and EXR are 8-bit registers,
word-size transfers are performed between them and
memory. The upper 8 bits are valid.
ANDC B CCR ∧ #IMM → CCR, EXR ∧ #IMM → EXR
Logically ANDs the CCR or EXR contents with
immediate data.
ORC B CCR ∨ #IMM → CCR, EXR ∨ #IMM → EXR
Logically ORs the CCR or EXR contents with immediate
data.
XORC B CCR ⊕ #IMM → CCR, EXR ⊕ #IMM → EXR
Logically exclusive-ORs the CCR or EXR contents with
immediate data.
NOP — PC + 2 → PC
Only increments the program counter.
