I/O
Data pin connected to USB.
I/O In case USB is not used, connect both pins to pull-up(DVCC3A) or pull-down resistor for protect
current flows it.
Output Internal clock output pin.
Operation mode;
Fix to AM1="0",AM0="1" for 16 bit external bus starting.
Input Fix to AM1="1",AM0="0" is prohibit to set.
Fix to AM1="1",AM0="1" for BOOT (32 bit internal Mask ROM) starting.
Fix to AM1="0",AM0="0" is prohibited to set.
Input Input pin in debug mode. (This pin is set to "Debug mode" by input "0".)
I/O High-frequency oscillator circuit connection pin.
I/O Low-frequency oscillator circuit connection pin.
