70 / 106 page  DF69 DC Fan Controller 6-16. Port B Digital Input Enable Register (pbdier), IO address = 0x0e Bit Reset R/W Description 7 1 WO Enable PB7 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB7 is assigned as AD input to prevent leakage current. If this bit is set to low, PB7 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 6 1 WO Enable PB6 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB6 is assigned as AD input to prevent leakage current. If this bit is set to low, PB6 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 5 1 WO Enable PB5 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB5 is assigned as AD input to prevent leakage current. If this bit is set to low, PB5 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 4 1 WO Enable PB4 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB4 is assigned as AD input to prevent leakage current. If this bit is set to low, PB4 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 3 1 WO Enable PB3 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB3 is assigned as AD input to prevent leakage current. If this bit is set to low, PB3 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 2 1 WO Enable PB2 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB2 is assigned as AD input to prevent leakage current. If this bit is set to low, PB2 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 1 1 WO Enable PB1 digital input and wake-up event. 1 / 0 : enable / disable. This bit should be set to low when PB1 is assigned as AD input to prevent leakage current. If this bit is set to low, PB1 can NOT be used to wake-up the system. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. 0 1 WO Disable PB0 digital input, external interrupt and wake up event. 1 / 0 : enable / disable. This bit should be set to low when PB0 is assigned as AD input to prevent leakage current. If this bit is set to low, PB0 can NOT be used as external interrupt pin and to wake up the system during power-down mode. Note: For ICE emulation, the function is disabled when this bit is “1” and “0” is enabled. Note: Due to the controlling polarity of this register is different between ICE and real chip. In order to unify the program for both ICE emulation and real chip to be the same one, please use the following command to write this register: “$ PBDIER 0xhh” ; For example: $ PBDIER 0xF0; It is used to enable the digital input and wakeup function of bit [7:4] of port B for both ICE and real chip, IDE will handle the difference between ICE and real chip automatically. ©Copyright 2018, PADAUK Technology Co.
