SADCON1 is a special function register (SFR) used to control the operation of the SA-ADC.
[Description of Bits]
The SARUN bit is used to start or stop SA-ADC conversion. Setting this bit to “1” starts A/D conversion and setting
it to “0” stops A/D conversion.
When SALP of SADCON0 is “0” and then A/D conversion on the channel with the largest channel number among the
selected ones is terminated, the SARUN bit is automatically set to “0”.
Notes:
Use the SA-ADC with high-speed clock oscillation (HSCLK) enabled in the frequency control register (FCON0).
The SA-ADC is available only when V
1.5MHz to 4.2 MHz.
Do not start A/D conversion in the state in which bits 1 (SACH1) and 0 (SACH0) of SA-ADC mode register 0 are “0”
and “0” respectively. When A/D conversion is started in this state, A/D conversion is not done while the A/D converter
is activated. Therefore, the SA-ADC result register is not updated, the A/D conversion termination interrupt is not
generated, A/D conversion is not terminated automatically, and SARUN remains “1”.
