DESCRIPTION
Serial flash ROM interface chip selection.
General-purpose I/O port 2 bit 2.
Clock output for serial flash.
*UBC, UBE and UBF version support 33 MHz frequency, but
UBE and UBF version use 16 MHz frequency as their default.
General-purpose I/O port 2 bit 3.
Transfer commands, addresses or data to serial flash. This pin
is connected to SI of serial flash.
Beep function for hardware monitor. This pin is low after system
reset.
Receive data from serial flash. This pin is connected to SO of
serial flash.
