PRODUCTION DATA
Table 7-3 describes the use, drive strength, and default state of analog and digital multiplexed pins at first-time power up and reset (nRESET pulled low).
Pin | BOARD-LEVEL CONFIGURATION AND USE | DEFAULT STATE AT FIRST POWER UP OR FORCED RESET | STATE AFTER CONFIGURATION OF ANALOG SWITCHES (ACTIVE, LPDS, AND HIB POWER MODES) | MAXIMUM EFFECTIVE DRIVE STRENGTH (mA) |
---|---|---|---|---|
29 | Connected to the enable pin of the RF switch (ANTSEL1). Other use is not recommended. | Analog is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
30 | Connected to the enable pin of the RF switch (ANTSEL2). Other use is not recommended. | Analog is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
45 | VDD_ANA2 (pin 47) must be shorted to the input supply rail. Otherwise, the pin is driven by the ANA2 DC/DC. | Analog is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
50 | Generic I/O | Analog is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
52 | The pin must have an external pullup of 100 kΩ to the supply rail and must be used in output signals only. | Analog is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
53 | Generic I/O | Analog is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
57 | Analog signal (1.8-V absolute, 1.46-V full scale) | ADC is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
58 | Analog signal (1.8-V absolute, 1.46-V full scale) | ADC is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
59 | Analog signal (1.8-V absolute, 1.46-V full scale) | ADC is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
60 | Analog signal (1.8-V absolute, 1.46-V full scale) | ADC is isolated. The digital I/O cell is also isolated. | Determined by the I/O state, as are other digital I/Os. | 4 |
