70 / 328 page  C8051F040/1/2/3/4/5/6/7 70 Rev. 1.5 6.1.1. Analog Input Configuration The analog multiplexer routes signals from external analog input pins, Port 3 I/O pins (programmed to be analog inputs), a High Voltage Difference Amplifier, and an on-chip temperature sensor as shown in Figure 6.2. Figure 6.2. Analog Input Diagram Analog signals may be input from four external analog input pins (AIN0.0 through AIN0.3) as differential or single-ended measurements. Additionally, Port 3 I/O Port Pins may be configured to input analog signals. Port 3 pins configured as analog inputs are selected using the Port Pin Selection register (AMX0PRT). Any number of Port 3 pins may be selected simultaneously as inputs to the AMUX. Even numbered Port 3 pins and odd numbered Port 3 pins are routed to separate AMUX inputs. (Note: Even port pins and odd port pins that are simultaneously selected will be shorted together as “wired-OR”.) In this way, differential mea- surements may be made when using the Port 3 pins (voltage difference between selected even and odd Port 3 pins) as shown in Figure 6.2. The High-Voltage Difference Amplifier (HVDA) will accept analog input signals and reject up to 60 volts common-mode for differential measurement of up to the reference voltage to the ADC (0 to VREF volts). The output of the HVDA can be selected as an input to the ADC using the AMUX as any other channel is selected for measurement. + - + - + - 9-to-1 AMUX (SE or DIFF) AMX0CF 10-Bit SAR ADC X TEMP SENSOR AGND AIN0.0 AIN0.1 AIN0.2 AIN0.3 AMX0SL 0 7 6 5 4 3 2 1 8 HV AMP HVCAP HVREF HVAIN - HVAIN + P3.6 P3.4 P3.2 P3.0 P3.7 P3.5 P3.3 P3.1 (WIRED-OR) (WIRED-OR) PAIN0EN PAIN2EN PAIN4EN PAIN6EN PAIN7EN PAIN5EN PAIN3EN PAIN1EN P3EVEN P3ODD + - |
