24.11 A/D Converter
Figure 24.4
Set ADCON0 (except bit 6), ADCON1 and ADCON2 registers when A/D conversion is stopped (before a trigger
occurs).
When the VCUT bit in the ADCON1 register is changed from “0” (Vref not connected) to “1” (Vref connected),
start A/D conversion after passing 1 µs or longer.
To prevent noise-induced device malfunction or latchup, as well as to reduce conversion errors, insert capacitors
between the AVCC, VREF, and analog input pins (ANi(i=0 to 7), AN0_i, AN2_i) each and the AVSS pin.
Similarly, insert a capacitor between the VCC1 pin and the VSS pin. Figure 24.4 is an example connection of each
pin.
Make sure the port direction bits for those pins that are used as analog inputs are set to “0” (input mode).
Also, if the TGR bit in the ADCON0 register = 1 (external trigger), make sure the port direction bit for the ADTRG
pin is set to “0” (input mode).
When using key input interrupts, do not use any of the four AN4 to AN7 pins as analog inputs. (A key input
interrupt request is generated when the A/D input voltage goes low.)
The φAD frequency must be 12MHz or less. Without sample-and-hold function, limit the φAD frequency to
250kHz or more. With the sample and hold function, limit the φAD frequency to 1MHz or more.
When changing an A/D operating mode, select analog input pin again in the CH2 to CH0 bits in the ADCON0
register and the SCAN1 to SCAN0 bits in the ADCON1 register.
