Preliminary
RXLCD Block Diagram
RXLCD Functional Description
RXLCD provides an LCD cache for REASM sub-entities. This cache holds the last four receive LCDs. The
sub-entities can request to load an LCD, read the LCD words, and update parts of the LCD.
12.38: RXLCD Cache Data Array Address Port
This register provides the read/write address for accessing the LCD cache data array. When the RXLCD
Cache Data Array Read/Write Port is read/written, this register is auto-incremented. When the last address is
read/written, the address rolls over to zero.
The cache is organized as 64 32-bit words. Each 16 words comprises an LCD. The first four words and the
last word of each LCD do not contain valid data and can not be written. These locations return zero on reads.
