functions of these pins (input block) are similarly fixed internally. As a result, the host interface

I/O pins (HDB7 to HDB0) also go to the high-impedance state.

This state is maintained while the HIFSD pin is low, and when the HIFSD pin returns to the high-

level state, the pins are restored to their normal operation as host interface pins.

Table 17.9 shows the scope of HIF pin shutdown in slave mode.

Notes: Slave mode: Single-chip mode and HI12E = 1

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 function is selected by means of a register setting

—: Pin not shut down
