Analog-to-Digital Converter (ATD10B8C)
Block Description
8.1
The ATD10B8C is an 8-channel, 10-bit, multiplexed input successive approximation analog-to-digital
converter. Refer to device electrical specifications for ATD accuracy.
The block is designed to be upwards compatible with the 68HC11 standard 8-bit A/D converter. In
addition, there are new operating modes that are unique to the HC12 design.
8.1.1
8.1.2
