DESCRIPTION
7
CC
Conversion Complete Flag (Read Only). The MAX7651/MAX7652 set this flag to 1 following a
conversion to indicate valid data in the ADDAT1 and ADDAT0 data SFRs (see below). The CC
bit is cleared to 0 when ADDAT1 is read by the CPU.
6
CCVT
Continuous Conversion Enable (Read/Write). When CCVT = 1, the ADC performs continuous
conversions at the rate of 224 clock cycles/conversion. Conversions continue until the MAX7651/
MAX7652 is reset or until CCVT is cleared, in which case conversions stops after the current
conversion ends.
5
CCIE
Conversion Complete Interrupt Enable (Read/Write). When CCIE = 1, interrupt 3 is generated at
the end of each conversion.
4
OVRN
Overrun Flag (Read Only). The MAX7651/MAX7652 set this flag to 1 whenever a conversion
completes while CC is set. The previous conversion result is overwritten. The OVRN bit is
cleared to 0 when ADDAT1 is read by the CPU.

Analog Input Multiplexer Select Bits. Used to establish input configurations for single-ended or
differential conversions (see Table 6).

SFR Address C5H
Note:
SFRs ADDAT1 and ADDAT0 contain the results of individual A/D conversions with the formats shown in Tables 8 and 9.
A read to ADDAT1 clears the CC and OVRN flags in ADCON.
