operation
Cautions 1. Make sure the period of <2> to <6> is 1
Remark Three types of A/D conversion result registers are available.
A/D conversion operations are performed continuously until bit 7 (ADCS) of the A/D converter mode register 0 (ADM0)
If a write operation is performed to the analog input channel specification register (ADS) during an A/D conversion
Reset signal generation clears the A/D conversion result register (ADCR, ADCRH, ADCRL) to 0000H or 00H.

2. If the timing of <2> is earlier than that of <4>, <2> may be performed any time.
• ADCR (16 bits): Store 10-bit A/D conversion value
• ADCRH (8 bits): Store the higher 8-bit A/D conversion value
• ADCRL (8 bits): Store the lower 8-bit A/D conversion value
