5 / 56 page  TC9318AFAG/AFBG 2006-07-27 5 Pin No. Symbol Pin Name Function and Operation Remarks 41~44 P2-0 P2-1/ADIN1 P2-2/ADIN2 P2-3/ DC-REF I/O port 2 /AD analog voltage input /AD analog voltage input /Reference voltage input 4 bit I/O ports. Input and output may be programmed in 1 bit units. Pins P2-1 through P2-2 can also be used for analog input to the built-in 6 bit, 2-channel A/D converter. Conversion time of the built-in A/D converter using the successive comparison method is 280 µs. The necessary pin can be programmed to AD analog input in 1 bit units, and P2-3 can be set to the reference voltage input. Internal power supply (VDD) or constant voltage (VEE) can be used as the reference voltage. In addition, constant voltage (VEE) can be input to the AD analog input so battery voltage, etc., can be easily detected. The reference voltage input, for which a built-in operational amp is used, has high impedance. The A/D converter, and their control are all executed by program. 45~46 P3-0 P3-1/BUZR I/O port 3 /Buzzer output 2 bit I/O ports, whose input/output can be programmed in 1 bit units. The P3-1 pin also functions as the output for the built-in buzzer circuit. The buzzer sound can be output in 254 different tones between 18.75 kHz and 147 Hz, and at a duty of 50%. The buzzer output, and all associated controls can be programmed. 47 MUTE Muting output port 1 bit output port. Normally, this port is used for muting control signal output. This pin can set the internal MUTE bit to “1” according to a change in the input of I/O port 1. MUTE bit output logic can be changed; PLL phase difference can also be output using this pin. 48 TEST TEST mode control input Input pin used for controlling TEST mode. High level indicates TEST mode, while low level indicates normal operation. The pin is normally used at low level or no-connection (NC). (a pull-down resistor is built-in). |
