These Ports can be selected as universal Counter i nput. A0 and A1 work as the FM IF and AM IF pin, independently. The maximum input frequency is 5MHz for AM IF (0.1Vp-p) and 20MHz (0.1Vp-p) for FM IF. These Posts can be selected for an A/D Converter Input. 2 Channel/8-Bit Analog-to-Digital Converter are used for the Sequential Comparison method by program. Reference Voltage of the A/D Converter is the same level of VDD (5V ¡ ¾ 10%) The A4,A5 Port can be used as event counter input 1,2. These Ports can be used as external interrupt pin. Port E is a bidirectional data port. These Ports can be selected as serial interface (SIO) 1. E0, E1 and E2 work as the serial output, serial input and serial clock pin, respectively. These Ports can be selected as serial interface (SIO) 2. E3, E4 and E5 work as the serial output, serial input and serial clock pin, respectively. The E7 Port can be used as BEEP output pin. Port F is a bidirectional data port.
