The power-up sequence of PT8R1002 is very simple mechanism. After power is applied to the PT8R1002, the activating RESET
signal into LOW for t is the only required operation. After this procedure, PT8R1002 will come into idle mode for waiting
RESET
transmit or receive operation indicated by Bluetooth baseband. Before this normal operation, all SPI register value should be
initialized even though its value is set by the default value. The initialized value will be provided by PTI. After activating
RESET signal, 13 or 16MHz baseband reference signal, DATACLK will be activated until execution of external power down
command through SPI interface.
