Precautions
In repeat sweep mode 1, all pins are used for A/D conversion with emphasis on the pin or pins selected using the A/
D sweep pin select bit. Table 1.61 shows the specifications of repeat sweep mode 1.

When set to 10-bit precision, the low 8-bits are stored in the even addresses and the high 2 bits in the odd ad-
dresses. When set to 8-bit precision, the low 8 bits are stored in the even addresses.
Sample and hold is selected by setting bit 0 of the AD control register 2 (address 03D4
