Notes: 1. Subclock functions (subactive mode, subsleep mode, and watch mode) are available in the U-mask and W-mask versions.
These functions cannot be used with the other versions.
See section 22A.7, Subclock Oscillator, for the method of fixing pins OSC1 and OSC2.
The H8S/2639 has no OSC1 and OSC2 pins.
2. These pins are used for the I2C bus interface.
The I2C bus interface is available as an option. The product equipped with the I2C bus interface is the W-mask version.
3. The FWE pin is for compatibility with the flash memory version.
The FWE pin is a NC pin in the mask ROM versions.
In the mask ROM version, the FWE pin must be left open or be connected to Vss.
