The S1D13A04 HAL includes six register access functions. The primary purpose of the
register access functions is to demonstrate how to access the S1D13A04 control registers
using the C programming language. Most programs that need to access the registers will
bypass the HAL and access the registers directly.
set. No S1D13A04 registers are changed
Index
The value read from the register.
Use caution in selecting the index and when interpreting values returned from
halReadReg8() to ensure the correct meaning is given to the values. Changing between big
endian and little endian will move relative register offsets.
Reads and returns the contents of one byte of an S1D13A04 register at the requested off-

system slowdowns and possibly memory faults, Offset should be a word
multiple.

the number of times to repeat the Value in memory. By including a count (or
loop) value this function can efficiently fill display memory.

32 bit offset to the register to read. Index is zero based from the beginning
of register address space. (e.g. if Index == 04h then the Memory Clock
Configuration register will be read and if Index == 8000h then the BitBLT
Control Register will be read)
