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
（ ）
1*
detects connection or disconnection of USB (in positive
logic)
Both positive and negative logics are prepared to detect both
connection and disconnection of USB.
detects connection or disconnection of USB (in negative
logic)
detects interrupts that are output from CXD5247
basically connects alarm interrupts of CXD5247
detects interrupts (SEN_IRQ_IN) that are output from
sensors
Interrupts from external sensor devices connected to SCU are
assumed.
