Programming Notes and Examples
Issue Date: 2002/08/21
The S1D13A04 HAL includes six memory access functions. The primary purpose of the
memory access functions is to demonstrate how to access display memory using the C
programming language. Most programs that need to access memory will bypass the HAL
and access memory directly.
Reads and returns the value of one byte of display memory.
Offset
The value of the byte at the requested offset.
Reads and returns the value of one word of display memory.
Offset
The value of the word at the requested offset.
Reads and returns the value of one dword of display memory.
Offset
The value of the dword at the requested offset.
Writes a byte into display memory at the requested address.
Offset
Value
Count
Nothing.
A 32 bit offset to the byte to be read from display memory
A 32 bit byte offset to the word to be read from display memory
To prevent system slowdowns and possibly memory faults, Offset should be
a word multiple.
A 32 bit byte offset to the dword to be read from display memory.
To prevent system slowdowns and possibly memory faults, Offset should be
a dword multiple.
A 32 bit byte offset to the byte to be written to display memory.
The byte value to be written to display memory.
The number of times to repeat Value in memory. By including a count (or
loop) value this function can efficiently fill display memory.
