FUNCTIONAL DESCRIPTION
The XA-H3 functions are described in the following sections.
Because all blocks are thoroughly documented in either the IC25 XA
Data Handbook , or the XA-H3 User Manual , only brief descriptions
are given in this datasheet, in conjunction with references to the
appropriate document.
XA CPU
The CPU is a 30 MHz implementation of the standard XA CPU core.
See the XA Data Handbook (IC25) for details. The CPU core is
identical to the G3 core. See caveat in next paragraph about the Bus
Interface Unit.
Bus Interface Unit (BIU)
This is the internal Bus, not the bus at the pins. This internal bus
connects the CPU to Memory Controller.
WARNING: Immediately after reset, always write BTRH = 51h,
followed by BTRL = 40h, in that order. Once written, do not change
the values in these registers. Follow these two writes with five
NOPS. Never write to the BCR register, it comes out of reset
initialized to 07h, which is the only value that will work.
