Swapping
The boot routine configures the PHIF16 by writing to the
PHIFC
register. Specifically, the external bus configuration, logical transfer size, and
byte swapping are controlled by the PMODE and PCFIG fields, the mode is controlled by the PSTROBE field, and the PODS/PDS active-
low/high configuration is controlled by the PSTRB field. After the download is complete, the boot routine returns the PHIF16 to its initial state
(configures it for Intelmode with an 8-bit external bus and 8-bit logical transfers).
This is the size of each input DMA transfer that the boot routine directs the MIOU0 to perform without core intervention. MIOU0 performs
input DMA from the PHIF16 block. The boot routine configures the input block size by programming the
ILEN0
register.
