49 / 65 page EM78P813 8-bit OTP Micro-controller __________________________________________________________________________________________________________________________________________________________________ * This specification is subject to change without notice. 49 2004/8/19 (V1.6) mode. When this bit is set to “0”, the Energy Detector works at low frequency mode. The difference between high frequency and low frequency is as follows. DEDPWR DEDCLK ENPLL Energy detector clock Main CLK 0 X X X Decision by ENPLL 1 0 0 32.768 KHz Disable 1 0 1 32.768 KHz Enable 1 1 0 3.5826 MHz Enable 1 1 1 3.5826 MHz Enable PS. “X” means don’t care Bit 3(CW_SMB) : Call Waiting / short message receiver switch 0 Short message mode select. ± 5.5% CAS tone accepted frequency range deviation.(Protocol : ± 5%) 1 Call Waiting mode select. CAS tone accepted frequency range deviation is decided on CODE Option Register bit 5 ( 1:for Europe and USA / 0:for China ) Bit 4 (WUEDD) : Wake-up control of Energy Detector (DED) output data 1/0 enable/disable Bit 5 (EDGE) : Wake-up and interrupt trigging edge control of Energy Detector (DED) output 1/0 Falling edge trig. / Rising edge and Falling edge trig. Bit 6(DEDD) : Output data of Differential Energy Detector (DED) If input signal from TIP/EGIN1 and RING/EGIN2 pin to Differential Energy Detector is over the threshold level setting at IOCE PAGE 2 bit 0 (DEDTHD), the DED will extract the zero-crossing pulse waveform corresponding to input signal. Bit 7 (VRSEL) : Reference voltage VR selection bit for Comparator 0 VR = VDD 1 VR = 2.0V When this bit is set to “0”, V2_0 ref. circuit will be powered off. 2.0V ref. circuit is only powered on when this bit and RA page2 bit 7(CMPEN) are all set to “1”. IOCF Interrupt Mask Register2 7 6 5 4 3 2 1 0 RBF/STD FSK/CW 0 UART DED CNT2 CNT1 TCC Bit 0~Bit 4, Bit6~Bit7 : Interrupt enable bits. 0/1 disable interrupt/enable interrupt Bit4: Undefined register. This bit must keep to 0. |
