I/O
62
I/O ^{Application CPU subsystem: JTAG interface.}
59
I/O
94
GND Connect to VSSC for ESD.
32
I
Used by the PMU to power up or power
down the on-chip regulators that supply
power to the Application CPU subsystem.
Also, when deasserted, the Application CPU
will be held in reset.
46
I/O SPI serial flash interface SPI clock output.
47
I/O External serial flash interface chip-select
(functionality cannot be remapped to
another purpose).
58
I/O SPI interface interrupt input.
48
I
Serial flash SPI MISO input.
49
O
Serial flash SPI MOSI output.
50
I
UART1 clear-to-send. Active-low, clear-to-
send signal for the HCI UART interface.
51
O
UART1 request-to-send. Active-low request-
to-send signal for the UART1 interface.
52
I
UART1 serial input. Serial data input for the
UART1 interface.
53
O
UART1 serial output. Serial data output for
the UART1 interface.
67, 68, 69, 70, 71, 72, PWR 1.2V core supply for APPS CPU.
73, 74
63, 64, 65
PWR Connect to 3.3V.
143
