Section 13 A/D Converter
Description
A/D Start
Starts or stops A/D conversion. When this bit is set to 1,
A/D conversion is started. When this bit is cleared to 0,
A/D conversion is stopped and the A/D converter enters
the idle state. In single or single-cycle scan mode, this bit
is automatically cleared to 0 when A/D conversion ends
on the selected single channel. In continuous scan mode,
A/D conversion is continuously performed for the
selected channels in sequence until this bit is cleared by
a software, reset, or in software standby mode or module
standby mode.
A/D Continuous Scan
Selects either single-cycle scan or continuous scan in
scan mode. This bit is valid only when scan mode is
selected.
0: Single-cycle scan
1: Continuous scan
When changing the operating mode, first clear the ADST
bit in the A/D control registers (ADCRs) to 0.
Reserved
These bits are always read as 1, and should only be
written with 1.
