Host Interface (HI08)
6.7.1 Interface Control Register (ICR)
The ICR is an 8-bit read/write control register by which the host processor controls the HI08
interrupts and flags. The DSP core cannot access the ICR. The ICR is a read/write register, which
allows the use of bit manipulation instructions on control register bits. Hardware and software
reset clear the ICR bits.

HLEND
Initialize
The host processor uses INIT to force initialization of the HI08 hardware.
During initialization, the HI08 transmit and receive control bits are configured.
Use of the INIT bit to initialize the HI08 hardware depends on the software
design of the interface. The type of initialization when the INIT bit is set
depends on the state of TREQ and RREQ The INIT command, which is local
to the HI08, configures the HI08 into the desired data transfer mode. When
the host sets the INIT bit, the HI08 hardware executes the INIT command.
The interface hardware clears the INIT bit after the command executes.
