Section 18 Host Interface X-Bus Interface (XBS)
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 18.7 shows the scope of HIF pin shutdown.

:
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 XBS function is selected by means of a register setting
