■
The mem_wr_32 command performs a burst-cycle 32-bit memory
write if the DWORD value is greater than 1. In a burst transaction, the
first data phase uses the data value provided in the command. The
subsequent data phases use values incremented sequentially by 1
from the data provided in the command argument.
mem_rd_32
The mem_rd_32 command performs a memory read with the address
provided in the command argument. This command can perform
single-cycle or burst 32-bit memory read depending on the value of the
dword
argument.
■
If the dword value is 1, the command performs a single-cycle
transaction.
■
If the dword value is greater than 1, the command performs a burst
transaction.
Syntax:
mem_wr_32(address, data, dword)
Arguments:
address
Transaction address. This value must be in
hexadecimal radix.
data
Data used for the first data phase. Subsequent
data phases use a value incremented sequentially
by 1. This value must be in hexadecimal radix.
dword
The number of
DWORD
s written during the
transaction. A value of 1 indicates a single-cycle
memory write transaction. A value greater than one
indicates a burst transaction. This value must be
an integer.
Syntax:
mem_rd_32(address, dword)
Arguments:
address
Transaction address. This value must be in
hexadecimal radix.
dword
The number
DWORD
s read during the transaction.
A value of one indicates a single-cycle memory
read transaction. A value greater than one
indicates a burst transaction. This value must be
an integer.
