under way. In that case, the top-priority A/D conversion completion flag cannot be
set, and the flag for previous normal A/D conversion cannot be cleared.
Two types of A/D conversion are supported: normal AD conversion and top-priority AD
conversion. Normal AD conversion is software activated by setting ADMOD0<ADS> to
"1." Top-priority AD conversion is software activated by setting ADMOD2<HPADCE> to
"1." 4 operation modes are made available to normal AD conversion. In performing
normal AD conversion, one of these operation modes must be selected by setting
ADMOD0<2:1> to an appropriate setting. For top-priority AD conversion, only one
operation mode can be used: fixed channel single conversion mode. Normal AD
conversion can be activated using the HW activation source selected by
ADMOD3<ADHS>, and top-priority AD conversion can be activated using the HW
activation source selected by ADMOD3<HADHS>. If this bit is "0," normal and top-priority
AD conversions are activated in response to the input of a falling edge through the
generated by the 16-bit timer 6, and top-priority AD conversion is activated in response to
TB5RG0 generated by the 16-bit timer 5. Software activation is still valid even after H/W
activation has been authorized.
(ADMOD4<ADRST1:0>) must be performed before starting A/D conversion. The HW
activation method must not be used to reactivate normal A/D conversion.
If ADMOD2<HPADCE> is set to "1" during normal A/D conversion, ongoing A/D
conversion is discontinued and top-priority A/D conversion starts; specifically, A/D
conversion (fixed channel single conversion) is executed for a channel designated by
ADMOD2<3:0>. After the result of this top-priority A/D conversion is stored in the storage
register ADREGSP, normal A/D conversion is resumed.
To reactivate normal A/D conversion while the conversion is under way, a software reset
ADTRG pin. If this bit is "1," normal AD conversion is activated in response to TB6RG0
When normal A/D conversion starts, the A/D conversion Busy flag (ADMOD0<ADBF>)
showing that A/D conversion is under way is set to "1." When top-priority A/D conversion
starts, the A/D conversion Busy flag (ADMOD2<ADBFHP>) showing that A/D
conversion is under way is set to "1." At that time, the value of the Busy flag for normal
A/D conversion before the start of top-priority A/D conversion is retained. The value of
the conversion completion flag EOCFN for normal A/D conversion before the start of
top-priority A/D conversion can also be retained.
