Action
Write bytes into memory.
Syntax
CmdMemWrite ptr, num,
Remarks
ptr |
The memory address to be written |
result |
Number of bytes to be written |
The data byte should immediately follow in the command buffer. If the number of bytes is not a multiple of 4, then
1, 2 or 3 bytes should be appended to ensure 4-byte alignment of the next command, these padding bytes can have any value.
The completion of this function can be detected when the value of REG_CMD_READ is equal to REG_CMD_WRITE.
Caution: if using this command, it may corrupt the memory of the FT800 if used improperly.
