279

––

Grouping:

A/D conversion operation

Description: In the A/D conversion mode (Q13 = 0), trans-

fers the high-order 4 bits (AD9–AD6) of register

AD to register B, and the middle-order 4 bits

(AD5–AD2) of register AD to register A. In the

comparator mode (Q13 = 1), transfers the high-

order 4 bits (AD7–AD4) of comparator register

to register B, and the low-order 4 bits (AD3–

AD0) of comparator register to register A.

Operation:

In A/D conversion mode (Q13 = 0),

(B)

← (AD9–AD6)

(A)

← (AD5–AD2)

In comparator mode (Q13 = 1),

(B)

← (AD7–AD4)

(A)

← (AD3–AD0)

(Q13 : bit 3 of A/D control register Q1)
