13. High Speed A/D Converter ⎯ SH7014 ⎯
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 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.

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.

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)
