Section 13 Host Interface (HIF)
Note:
13.4.5
HIFIICR is a 32-bit register used to issue interrupts from an external device connected to the HIF
to the on-chip CPU. Access to HIFIICR by an external device should be performed with HIFIICR
specified by bits REG5 to REG0 in HIFIDX and the HIFRS pin low.

HIF Internal Interrupt Control Register (HIFIICR)
This bit can be only written to by an external device when the HIFRS pin is low. It
cannot be written to by the on-chip CPU. Changing the HIFRAM banks accessible from
an external device by setting the BMD and BSEL bits in HIFSCR does not affect the
setting of this bit.

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Address Auto-Increment/Decrement
This bit is valid only when the LOCK bit is 1. The value of
HIFADR is automatically incremented by 4 or
decremented by 4 according to the setting of this bit each
time reading or writing of HIFRAM is performed.
0: Auto-increment mode (+4)
1: Auto-decrement mode (−4)
