Definition
Load 64-bit data from memory to an internal register of the chip.
Operands
This command has the following operands:
Example
LOAD64 SCRATCHA0, 4, data_buf
LOAD64 SCRATCHA3, 2, DSAREL (0x02)
Register
Is one of the register names in the chip operating register set.
Byte Count
Is the number of bytes [1:4] to be transferred from the
source_address.
DSA Relative
Indicates that the source_address is an offset and should be
added to the DSA register to obtain the physical address
(DSA relative).
Source Address
Is the physical address or offset from the DSA to obtain the
physical address of the data to be loaded into the register.
