• Manufacturer Part Number: UPD784026
• Description: 16/8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

Cautions 1. When the STOP mode is used in a system that uses an external clock, the EXTC bit of the OSTS
2. The CS bit of the A/D converter mode (ADM) register should be cleared (0).
3. D/A converter operation is not stopped simply by setting the STOP mode. In order to reduce the
must be set (1). If STOP mode setting is performed in a system to which an external clock is input
when the EXTC bit of the OSTS is cleared (0), the the current consumption will increase.
When setting the EXTC bit of OSTS to 1, be sure to input a clock in phase reverse to that of the
clock input to the X1 pin, to the X2 pin (refer to 4.3.1 Clock Oscillator).
current consumption, the DACEn (n = 0, 1) bits of the D/A converter mode register (DAM) must
both be cleared (0). When DACEn is cleared (0), the ANOn (n = 0, 1) pin output level becomes high-
impedance.
