VDD_PADS is the supply to all the I/O domains for PIO, UART, PCM, LED and
RST#.
Boot Modes
Application of a voltage greater than 3.1V correctly boots the module, the module
can be powered down by removing the fixed supply voltage or by pulling
VREGEN low. If the fixed supply voltage remains, restart the module by pulling
VREGEN high.
BC127/BC127-HD/BC127-EXT to Wake-Up an
External Processor on Connection
With GPIO control disabled, the BC127/BC127-HD/BC127-EXT has PIOs that will
go high when a Bluetooth connection is established. Please refer to the Melody
Manual for more details.
