Notice: This is not a final specification.

Some parametric limits are subject to change.

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 DA conversion register of the other D/A converter being “0016”.
