6.6 ADC Control Registers
The ADC contains thirteen registers—one control register (ANCTR) and twelve
data buffers (each associated with one of the ADIN pins). ANCTR controls the
operating conditions, and the read-only data buffers hold the results of the A/D
conversions.
AN0BUF–AN11BUF: ADIN0–ADIN11 Conversion Data Buffers x’00FF00’–x’00FF1C’
These buffers hold the 8-bit A/D conversion data. Their value is unknown
after reset.
