LPCD_Q_Result bits Bit Symbol Description 7RFU - 6 LPCD_Irq_Clr If set no LPCD IRQ is raised any more until the next low-power card detection procedure. Can be used by software to clear the interrupt source. 5 to 0 LPCD_Q_Result Shows the result of the last ow power card detection (Q-Channel). Table 179. PinEn register (address 44h) Bit 7 6 5 4 3 2 1 0 Symbol SIGIN_EN CLKOUT_EN IFSEL1_EN IFSEL0_EN TCK_EN TDI_EN TDO_EN TMS_EN Access rights r/w r/w r/w r/w r/w r/w r/w r/w Table 180. PinEn bits Bit Symbol Description 7 SIGIN_EN Enables the output functionality on SIGIN (pin 5). The pin is then used as I/O. 6 CLKOUT_EN Enables the output functionality of the CLKOUT (pin 22). The pin is then used as I/O. The CLKOUT function is switched off. 5 IFSEL1_EN Enables the output functionality of the IFSEL1 (pin 27). The pin is then used as I/O. 4 IFSEL0_EN Enables the output functionality of the IFSEL0 (pin 26). The pin is then used as I/O. 3 TCK_EN Enables the output functionality of the TCK (pin 4) of the boundary scan interface. The pin is then used as I/O. If the boundary scan is activated in EEPROM, this bit has no function. 2 TDI_EN Enables the output functionality of the TDI (pin 2) of the boundary scan interface. The pin is then used as I/O. If the boundary scan is activated in EEPROM, this bit has no function. 1 TDO_EN Enables the output functionality of the TDO (pin 1) of the boundary scan interface. The pin is then used as I/O. If the boundary scan is activated in EEPROM, this bit has no function. 0 TMS_EN Enables the output functionality of the TMS (pin 3) of the boundary scan interface. The pin is then used as I/O. If the boundary scan is activated in EEPROM, this bit has no function. Table 181. PinOut register (address 45h) Bit 7 6 5 4 3 2 1 0 Symbol SIGIN_OUT CLKOUT_OUT IFSEL1_OUT IFSEL0_OUT TCK_OU T TMI_OUT TDO_OUT TMS_OUT Access rights r/w r/w r/w r/w r/w r/w r/w r/w |
