Note: * When carrying out debugging using the E10A emulator, this pin is used for mode switching.
It should be connected to VSS when using the E10A emulator and connected to VCC when
using a normal user system. When a boundary scan test is performed with the H-UDI, user
mode must be used. A boundary scan test cannot be performed in ASE mode.
