... As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port B also serves the functions of various special features of the ATmegaT. 4958BS–AUTO–01/09 ATA6285N/ATA6286N [Preliminary] Alternate Alternate Function 1 Function 2 – ...

... RF low-cost transmission systems at data rates Kbits/s Manchester coding and 40 Kbits/s NRZ coding. The transmitting frequency range is 313 MHz to 317 MHz (ATA6285N) and 432 MHz to 448 MHz (ATA6286N), respectively. It can be used in both FSK and ASK sys- tems. Due to its shorten crystal oscillator settling time it is well suited for Tire Pressure Monitoring (TPMS) and for Passive Entry Go applications ...

... CLK output activation. This means an additional wait time of necessary before the PA can be switched on and the data transmission can start. This results in a significantly lower time of about 0.85 ms between enabling the ATA6285N/ATA6286N and the beginning of the data transmission which saves battery power especially in tire pressure moni- toring systems ...

After typically 0.6 ms, the CLK driver is activated automatically (the microcontroller waits until the XTO and CLK are ready). After another time period of 250 µs, the PLL is locked and ready to transmit. The output power can then be modulated by means of pin ASK ...

... CLK Output An output CLK signal of 1.64 MHz (ATA6285N operating at 315 MHz) and 1.69 MHz (ATA6286N operating at 433.92 MHz) is provided for a connected microcontroller. The delivered signal is CMOS-compatible with a High and Low time of >125 ns if the load capacitance is lower than 20 pF. The CLK output is Low in power-down mode due to an internal pull-down resistor. ...
