Table General Purpose Input/Output (GPIO)-27 shows I/O pins that can be used for event detection. As for I/O
pins that can be used for interrupt (refer to 3.2.4.2), bit-field names of interrupt factor registers are described in the
“Interrupt Factor” field of the table. For interrupt factors, refer to Chapter 3.3 (interrupt).

I/O Pin Description
Interrupt Factor
P1z_00
USB_VBUS
detects connection or disconnection of USB (in positive
logic)
Both positive and negative logics are prepared to detect both
connection and disconnection of USB.
USBVBUS
P1z_00
USB_VBUS_X
detects connection or disconnection of USB (in negative
logic)
USBVBUSN
P11_00
PMIC_INT
detects interrupts that are output from CXD5247
basically connects alarm interrupts of CXD5247
PMIC_INT
P1e_00
SEN_INT
detects interrupts (SEN_IRQ_IN) that are output from
sensors
Interrupts from external sensor devices connected to SCU are
assumed.
