Bit 3

⎯Scan Mode (SCAN): Selects either single mode or scan mode for the A/D conversion

operation mode. See section 13.4, Operation, for details on single mode and scan mode operation.

Set the SCAN bit only while conversion is halted.

Bit 3

SCAN

Description

Single mode

(initial value)

Scan mode

Bit 2

⎯Simultaneous Sampling (DSMP): Enables or disables the simultaneous sampling of two

channels. See section 13.4.6, Simultaneous Sampling Operation, for details on simultaneous

sampling.

Set the DSMP bit only while conversion is halted.

Bit 2

DSMP

Description

Normal sampling operation

(initial value)

Simultaneous sampling operation

Bits 1 and 0

⎯Buffer Enable 1, 0 (BUFE1, BUFE0): These bits select whether to use the

ADDRB to ADDRD as buffer registers.

Set the BUFE1 and BUFE0 bits only while conversion is halted.

Bit 1

BUFE1

Bit 0

BUFE0

Description

Normal operation

(initial value)

ADDRA and ADDRB buffer operation: conversion result

→

ADDRA

→ ADDRB (ADDRB is the buffer register)

ADDRA and ADDRC, also ADDRB and ADDRD buffer

operation: conversion result 1

→ ADDRA → ADDRC,

conversion result 2

→ ADDRB → ADDRD (ADDRC and

ADDRD are buffer registers)

ADDRA to ADDRD buffer operation: conversion result

→

ADDRA

→ ADDRB → ADDRC → ADDRD (ADDRB to ADDRD

are buffer registers)
