(16) Multiplication/division instruction

- 16 bits × 8 bits (7 instruction cycle times)

- 16 bits / 8 bits (7 instruction cycle times)

(17) 3 oscillation circuits

- Built-in RC oscillation circuit used for the system clock

- Built-in VCO circuit used for the system clock and OSD

- X’tal oscillation circuit used for base timer, system clock and PLL reference

(18) Standby function

- HALT mode The HALT mode is used to reduce the power dissipation. In this operation mode, the program execution is stopped. This mode can be released by the interrupt request or the system reset.

- HOLD mode The HOLD mode is used to stop the oscillations; RC (internal), VCO, and X’tal oscillations. This mode can be released by the following conditions.

Pull the reset terminal (

•

Feed the selected level to either P70/INT0 or P71/INT1.

•

) to low level.
