Fig. 79 Bit configuration of A-D control register 1
Fig. 80 Bit configuration of A-D control register 2
Notes 1: Invalid in the one-shot mode and repeat mode. (Each of these bits may be “0” or “1”.)
2: When using pin AN7, make sure that the D-A0 output enable bit (bit 0 at address 9616) = “0” (output disabled).
3: Once this bit is cleared from “1” to “0”, it is necessary to wait for 1 s or more before the A-D conversion starts.
4: Rewriting to each bit of the A-D control register 1 must be performed while A-D conversion is stopped.
0
A-D sweep pin select bits (Note 1)
(Valid in the single sweep mode and repeat sweep mode.)
0 0 : AN0, AN1 (2 pins)
0 1 : AN0–AN3 (4 pins)
1 0 : AN0–AN4 (5 pins)
1 1 : AN0–AN7 (8 pins) (Note 2)
A-D operation mode select bit 1
0: Modes other than repeat sweep mode 1
1: Repeat sweep mode 1
Resolution select bit
0: 8-bit resolution mode
1: 10-bit resolution mode
A-D conversion frequency (
φAD) select bit 1
Fix this bit to “0”.
VREF connection select bit (Note 3)
0 : VREF is connected.
1 : VREF is disconnected.
“0” at read.
