A/D converter characteristics
NOTES:
1. 8-bit A/D mode: When the conversion mode selection bit (bit 7 of address 003816) is “1”.
2. 10-bit A/D mode: When the conversion mode selection bit (bit 7 of address 003816) is “0”.
NOTES:
1. 8-bit A/D mode: When the conversion mode selection bit (bit 7 of address 003816) is “1”.
2. 10-bit A/D mode: When the conversion mode selection bit (bit 7 of address 003816) is “0”.
D/A converter characteristics
NOTES:
1. Using one D/A converter, with the value in the other DAi conversion register (i=1, 2) being “0016”.
