APPLICATION NOTES
Operation During Boot Up
Clock Selection
HCI Transport Selection
1 Semiconductor
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 : 8-bit
BBWSEL = H : 16-bit
The CPU clock supply source is selected according to external pin SCLKSEL.
SCLKSEL = L : Use 32/16/8/4 MHz clock that was divided down from the internal PLL output of 192 MHz
SCLKSEL = H : Use external pin XCLK.
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 : Use 1 MHz clock that was divided down from the internal PLL output (192 MHz).
TXCSEL = H : Use external pin TXC_IN.
Note: This clock can also be set by the CLKCNT register in the CTL/WDT block.
HCI is selected (USB/UART) according to the logical value of GPIO0 at initial powerup of ML7051LA.
GPIO0 = L
GPIO0 = H
