Connect to resonator or crystal, or external clock source. I XTI 8 Oscillator drive output. Connect to resonator or crystal. O XTO 7 Ground Pwr Vss 6 +5 supply Pwr Vdd 5 Reset input, active low reset I RST 4 SPI Clock. In Master mode is an output; in Slave mode is an input I/O PP SCK 3 Master-In / Slave Out SPI line. Not used in Master/Slave SPI mode. In Slave mode outputs data to host (out only). I/O PP MISO 2 Master-Out / Slave In SPI line. In Master/Slave SPI mode is used for both communication directions. In Slave SPI mode is the data input (in only).
