Legend:

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 function is selected by means of a register setting

—: Pin not shut down

Note:

Slave mode: Single-chip mode and HI12E = 1
