16.7
16.7.1
Operation of the A/D converter can be disabled or enabled using the module stop control register.
The initial setting is for operation of the A/D converter to be halted. Register access is enabled by
clearing module stop mode. For details, refer to section 22, Power-Down Modes.
16.7.2
This LSI’s analog input is designed so that conversion precision is guaranteed for an input signal
for which the signal source impedance is 10 k or less. This specification is provided to enable
the A/D converter’s sample-and-hold circuit input capacitance to be charged within the sampling
time; if the sensor output impedance exceeds 10 k , charging may be insufficient and it may not
be possible to guarantee the A/D conversion accuracy. However, if a large capacitance is provided
externally for conversion in single mode, the input load will essentially comprise only the internal
input resistance of 10 k , and the signal source impedance is ignored. However, since a low-pass
filter effect is obtained in this case, it may not be possible to follow an analog signal with a large
differential coefficient (e.g., 5 mV/ s or greater) (see figure 16.6). When converting a high-speed
analog signal or conversion in scan mode, a low-impedance buffer should be inserted.
