267 / 715 page  9.3.4 Input Pull-Up Transistors Port 5 has built-in MOS pull-up transistors that can be controlled by software. These input pull-up transistors can be used in modes 1 and 2. They can be turned on and off individually. In modes 1 and 2, when a P5PCR bit is set to 1 and the corresponding P5DDR bit is cleared to 0, the input pull-up transistor is turned on. The input pull-up transistors are turned off by a reset and in hardware standby mode. In software standby mode they retain their previous state. Table 9-5 summarizes the states of the input pull-ups in each mode. Table 9-5 Input Pull-Up Transistor States (Port 5) Hardware Software Mode Reset Standby Mode Standby Mode Other Modes 1 Off On/off 2 3 Off 4 Legend Off: The input pull-up transistor is always off. On/off: The input pull-up transistor is on if P5PCR = 1 and P5DDR = 0. Otherwise, it is off. 249 |
