19.5 Interrupt of 8-/10-bit A/D Converter
The 8-/10-bit A/D converter can issue an interrupt request when data is set to the A/D data register by A/D
conversion. This also corresponds to the EI
n Interrupt of 8-/10-bit A/D converter
The interrupt control bits and interrupt factors of the 8-/10-bit A/D converter are shown in Table 19-7.

Interrupt factor
When the A/D conversion is started and then the A/D conversion result is set to the A/D data register
(ADCR), the INT bit of the A/D control status register higher (ADCSH) is set to 1. When the interrupt request
is already enabled (ADCSH: INTE = 1) at this point, an interrupt request is output to the interrupt controller.

OS function of 8-/10-bit A/D converter
The 10-bit A/D converter can transfer the A/D conversion result to memory by using the EI
During this operation, the function to protect the converted data operates to suspend A/D conversion until
A/D-converted data is transferred to memory and the INT bit is cleared, preventing loss of data.
