APPLICATION NOTES
Operation During Boot Up
Clock Selection
HCI Transport Selection
1 Semiconductor
HCI is selected (USB/UART) according to the logical value of GPIO0 at initial powerup of
ML70Q5111LA.
Remapping during boot up is performed according to external pins REMAP[1:0].
Bit width that corresponds to BANK0 during boot up is set according to external pin BBWSEL.
BBWSEL = L :
BBWSEL = H :
The CPU clock supply source is selected according to external pin SCLKSEL.
SCLKSEL = L :
SCLKSEL = H :
Note: The clock supply source can also be set by the CLKCNT register in the CTL/WDT block.
Bluetooth transmission clock is selected according to external pin TXCSEL.
TXCSEL = L :

TXCSEL = H :
Note: This clock can also be set by the CLKCNT register in the CTL/WDT block.
