5.3
The 56F8006/56F8002 series contain a dual access memory. It can be accessed from core primary data buses (XAB1; CDBW;
CDBR) and secondary data buses (XAB2; XDB2). Addresses in data memory are selected on the XAB1 and XAB2 buses. Byte,
word, and long data transfers occur on the 32-bit CDBR and CDBW buses. A second 16-bit read operation can be performed
in parallel on the XDB2 bus.
Peripheral registers and on-chip JTAG/EOnCE controller registers are memory-mapped into data memory access. A special
direct address mode is supported for accessing a first 64-location in data memory by using a single word instruction.
