This function is selected when the LED driver is enabled.
Dedicated pins for the FL driver output.
General-purpose I/O port
External trigger input pin for input capture 0
External factor input pin for external interrupt input 0
This pin is only accepted when it is enabled by the EN0 bit.
General-purpose I/O port
External trigger input pin for input capture 1
External factor input pin for external interrupt input 1
This pin is only accepted when it is enabled by the EN1 bit.
General-purpose I/O port
Serial data input pin for serial I/O channel 0
This pin is always effective when channel 0 is under input operation.
General-purpose I/O port
Serial clock I/O pin for serial I/O channel 0
This pin is effective when the channel-0 clock output is enabled.
General-purpose I/O port
Serial data output pin for serial I/O channel 0
This pin is effective when the channel-0 serial data output is
enabled.
General-purpose I/O port
Serial data input pin for serial I/O channel 1
This pin is always effective when channel 0 is under input operation.
General-purpose I/O port
Serial clock I/O pin for serial I/O channel 1
This pin is effective when the channel-0 clock output is enabled.
This pin is a general-purpose I/O port.
Serial data output pin for serial I/O channel 1
This pin is effective when the channel-0 serial data output is
enabled.
General-purpose I/O port (However, the N ch is open drain.)
2
Data I/O pin for the I C interface. This function is effective when
