64 bit Wide On Board Memory FLASH
The TVME8300 provides 8 Mbyte of 64 bit wide board mounted Memory FLASH using four 1 M x
16 bit FLASH devices.
The Memory FLASH address range is 0xFF00_0000 to 0xFF7F_FFFF.
For writes to the Memory FLASH double-word (64 bit) transfer sizes must be used.
Writes to the Memory FLASH must be enabled in the Utility Control Register.
For 64 bit writes to the Memory Flash, the processor may issue a single-beat 64 bit write, using a
caching-inhibited stfd (store floating point double), with the data in a Floating Point Register (FPR).
