8. A/D converter
In the emulator, the evaluation chip and the slave chip are used to implement functions of Unit
0 and Units 1 and 2, 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.
9. P66 and P67
When P63 is selected as the TXD6 output in the actual device, P66 becomes an I/O port output
pin; however, it does not become an I/O port output pin in the emulator. Also, when P65 is
selected as the SCK6 output, P67 becomes an I/O port output pin, but it does not become an
I/O port output pin in the emulator. Ensure that the corresponding DDR bit is set to "1" if P66
or P67 is to be used as an I/O port output pin in the emulator.
