Notes: O: Pins shut down by shutdown function
The IRQ2/ADTRG input signal is also fixed in the case of P90 shutdown, the
TMCI1/HSYNCI signal in the case of P43 shutdown, and the TMRI/CSYNCI in the case
of P45 shutdown.
∆: Pins shut down only when the HIF:XBS function is selected by means of a register
setting
—: Pin not shut down
