Function

Output/Input buffer drive-register for standby-mode

(Purpose and method of using)

• This register is used to set each pin-status at stand-by mode.

• All ports have this format’s register. (“x” means port-name.)

• For each register, refer to 3.5 Function of Ports.

• Before “HALT” instruction is executed, set each register pin-status. They will be

effective after CPU executes “HALT” instruction.

• This register is effective in all stand-by modes (IDLE2, IDLE1 or STOP).

• This register is effective when using PMC function. For details, refer to PMC

section.


The truth table to control Output/Input-buffer is below.

Note1: OE means an output enable signal before stand-by mode. Basically, PxCR is used as OE.

Note2: “n” in PxnD means bit-number of PORTx.
