7. A/D converter

In the emulator, the evaluation chip and the slave chip are used to implement functions of Unit

0 and Unit 1, respectively, of the A/D converter. For this reason, when the A/D control register

(ADCR) has been set to start A/D conversion (with synchronization of units) by an external

trigger from the ADTRG0 pin, the interrupt timing at the end of the A/D conversion will be

different between Unit 0 and Unit 1.

8. Clock Input to the USB Module

While using the emulator, the frequency of the clock signal supplied to the USB module is

fixed to 48 MHz regardless of the EXTAL input by the user.
