Description
Leave unconnected
Notes:
(1)
To enable the regulator the VREG_EN pin needs to be either pulled high or left unconnected. This
keeps compatibility with BlueCore2-ROM as the corresponding pin on BlueCore2-ROM was designated
as a not connect pin. In this situation the BlueCore4-ROM regulator is permanently on replicating the
BlueCore2-ROM that has no regulator enable pin.
(2) _{Positive supply for PIO[3:0] and PIO[11:8]}
(3) _{Positive supply for SPI/PCM ports and PIO[7:4]}
