60 / 118 page  EM78P372K 8-bit Microcontroller 52 Product Specification (V1.4) 05.11.2016 (This specification is subject to change without prior notice) In EM78P372K, each individual interrupt source has its own interrupt vector as depicted in the table below. Interrupt Vector Interrupt Status Priority * 003H External interrupt 2 006H Port 5, P70, P71 pin change 3 009H TCC overflow interrupt 4 00CH AD conversion complete interrupt 5 00FH Comparator interrupt 6 012H PWM1 period match interrupt 7 015H PWM2 period match interrupt 8 018H PWM1 duty match interrupt 9 01BH PWM2 duty match interrupt 10 021H Low Voltage Detector interrupt 1 Note: *Priority: 1 = highest ; 11 = lowest priority 7.7 Analog-to-Digital Converter (ADC) The analog-to-digital circuitry consists of an 8-bit analog multiplexer; three control registers (AISR/R8, ADCON/R9, and ADOC/RA), three data registers (ADDATA1/RB, ADDATA1H/RC, and ADDATA1L/RD) and an ADC with 12-bit resolution as shown in the functional block diagram below. The analog reference voltage (Vref) and the analog ground are connected via separate input pins. Connecting to an external VREF is more accurate than connecting to an internal VDD. The ADC module utilizes successive approximation to convert the unknown analog signal into a digital value. The result is fed to the ADDATA, ADDATA1H, and ADDATA1L. Input channels are selected by the analog input multiplexer via the ADCON register Bits ADIS1 and ADIS0.
