Table 1-8. System Control Instructions
Instruction Size* Function
RTE -- Returns from an exception handling routine.
SLEEP -- Causes a transition to power-down state.
Rs → CCR, #Imm → CCR
LDC B
Moves immediate data or general register contents to the condition code
register.
CCR → Rd
STC B
Copies the condition code register to a specified general register.
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.
* Size: Operand size
B: Byte
Table 1-9. Block Data Transfer Instruction
Instruction Size Function
if R4L ≠ 0 then
EEPMOV --
else next;
Moves a data block according to parameters set in general registers
R4L, R5, and R6.
R4L: size of block (bytes)
R5: starting source address
R6: starting destination address
Execution of the next instruction starts as soon as the block transfer is completed.
This instruction is for writing to the large-capacity EEPROM provided on chip with some
models in the H8/300L Series. For details see the applicable hardware manual.
