11 / 20 page LC823430TA No.A2171-11/20 Pin Functions JTAG Pin name Pol. Type Description Num. JTDO/ P1C -/ - O/ B JTAG test data output/ General purpose port 1 JTDI/ P1D -/ - I/ B JTAG test data input/ General purpose port. The input level of the terminal JTDI is taken by rising edge of the terminal NRES. The value can be read as a register, and can be used as the operation mode setting. 1 JTMS/ P1E -/ - I/ B JTAG test mode selection/ General purpose port The input level of the terminal JTMS is taken by rising edge of the terminal NRES. The value can be read as a register, and can be used as the operation mode setting. 1 JTCK/ P1F Pos/ - I/ B JTAG test clock/ General purpose port 1 Total 4 RTC Pin name Pol. Type Description Num. XIN32K Pos I 32.768kHz oscillation amplifier input (XT1) 1 XOUT32K - O 32.768kHz oscillation amplifier output (XT1) 1 VDET (RTCRSTB) Neg Neg I I Power supply watch comparison input There is an optional bonding as RTC reset input. 1 RTCINT (PWRON) Neg - O O RTC interrupt output (Normal: Hi-z, the interrupt generation: Low output). There is an optional bonding as main power supply ON/OFF control. 1 BACKUPB (LINEFIXB) Neg Neg I I RTC operation mode selection There is an optional bonding as RTC isolator cutting and the connection. 1 VDDRTC - P RTC block power supply. 1 VSSRTC - P RTC ground pin. 1 Total 7 |
