(1) Operating at A-D conversion mode
The A-D conversion mode is set by setting the bit 3 of register Q2 to “0.”
(2) Successive comparison register AD
Register AD stores the A-D conversion result of an analog input in
10-bit digital data format. The contents of the high-order 8 bits of
this register can be stored in register B and register A with the
TABAD instruction. The contents of the low-order 2 bits of this reg-
ister can be stored into the high-order 2 bits of register A with the
TALA instruction. However, do not execute this instruction during A-
D conversion.
When the contents of register AD is n, the logic value of the com-
parison voltage V
ref
generated from the built-in DA converter can
be obtained with the reference voltage V
DD
by the following for-
mula:

(4) A-D conversion start instruction (ADST)
A-D conversion starts when the ADST instruction is executed. The
conversion result is automatically stored in the register AD.
(5) A-D control register Q1
Register Q1 is used to select one of analog input pins.
(6) A-D control register Q2
Register Q2 controls the A-D conversion mode. The A-D conver-
sion mode is selected when the bit 3 of register Q2 is “0,” and the
comparator mode is selected when the bit 3 of register Q2 is “1.”

(3) A-D conversion completion flag (ADF)
A-D conversion completion flag (ADF) is set to “1” when A-D con-
version completes. The state of ADF flag can be examined with the
skip instruction (SNZAD). Use the interrupt control register V2 to
select the interrupt or the skip instruction.
The ADF flag is cleared to “0” when the interrupt occurs or when
the next instruction is skipped with the skip instruction.
