Section 14 A/D Converter
14.2.4
A/D control/status register 0 (ADCSR1) is an 8-bit readable/writable register whose functions
include selection of the A/D conversion mode for A/D1.
ADCSR1 is initialized to H'00 by a power-on reset, and in hardware standby mode and software
standby mode.
Note:
Bit 7—A/D End Flag (ADF): Same as ADF in ADCSR0.
Bit 6—A/D Interrupt Enable (ADIE): Same as ADIE in ADCSR0.
Bit 5—A/D Start (ADST): Same as ADST in ADCR0.
Bit 4—Scan Mode (SCAN): Selects single mode or scan mode for A/D1. To prevent incorrect
operation, ensure that the ADST bit is cleared to 0 before switching the operating mode.
Bit 4:

0
1
For details of the operation in single mode and scan mode, see section 14.4, Operation.
Bit 3—Clock Select (CKS): Same as CKS in ADCR0.
Bit 2—Reserved: This bit is always read as 0, and should only be written with 0.
