13. High Speed A/D Converter ⎯ SH7014 ⎯
Bit 7⎯A/D End Flag (ADF): This status flag indicates that A/D conversion has ended.
Bit 7
ADF
0
1
Description
[Clear conditions]
(initial value)
• With ADF = 1, by reading the ADF flag then writing 0 in ADF
• When the DMAC is activated by an ADI interrupt
[Set conditions]
• Single mode: When A/D conversion ends after conversion for all
designated channels (during buffer operation, this is not set until
operation of the specified buffer has ended)
• Scan mode: After one round of A/D conversion for all specified
channels
Bit 6⎯A/D Interrupt Enable (ADIE): Enables or disables interrupt requests (ADI) after A/D
conversion ends. Set the ADIE bit while conversion is suspended.
Bit 6
ADIE
0
1
Description
Disables interrupt requests (ADI) after A/D conversion ends
(initial value)
Enables interrupt requests (ADI) after A/D conversion ends
Bit 5⎯A/D Start (ADST): Selects start or stop for A/D conversion. A 1 is maintained during A/D
conversions.
The ADST bit can be set to 1 by software, or timer conversion start triggers.
Bit 5
ADST
0
1
Description
A/D conversion halted
(initial value)
• Single mode: Start A/D conversion. Automatically cleared to 0 after
conversion for the designated channel ends.
• Scan mode: Start A/D conversion. Continuous conversion until 0
cleared by software.
