Hardware Design Considerations
3.4.3
After a power-on reset, the PLL is bypassed and the device is directly clocked from the
slowly during the boot process. After the boot program is loaded, it can enable the PLL and start the device operating at a higher
speed. The MSC7119 can boot from an external host through the HDI16 or download a user program through the I
boot operating mode is set by configuring the
See the MSC711x Reference Manual for details of boot program operation.
3.4.3.1
If the MSC7119 device boots from an external host through the HDI16, the port is configured as follows:

Operate in Non-DMA mode.
Operate in polled mode on the device side.
Operate in polled mode on the external host side.
External host must write four 16-bit values at a time with the first word as the most significant and the fourth word as
the least significant.
