Note 11. All digital input pins are held to VSS2-5.
Note 12. It is 33 [mA] (typ) when the OMCLK/XTI pin is supplied a 6.144MHz external clock and the output port is in
slave mode.
Note 13. It is 82 [mA] (typ) when the OMCLK/XTI pin is supplied a 6.144MHz external clock and the output port is in
slave mode.
Note 14. It is 83 [mA] (typ) when the OMCLK/XTI pin is supplied a 6.144MHz external clock and the output port is in
slave mode.
