5.10.3. Timing Modes
The timing modes are divided into the following parameters:
The burst read, burst write, and single write timings may be set separately for CPU cycles and alternate masters.
Alternate masters include VL bus masters, ISA masters, and DMA cycles. This function allows alternate masters to run
at a slower timing mode. This may be useful for the following reasons:
The three Burst read modes are shown below.
Revision 1.0
The 4041 must generate parity for DRAM write cycles for the alternate master (the CPU parity is used for CPU
The CPU is a more controlled part on the board. Its timing may be able to be assumed better than the worst
The system designer may optimize for the last bit of CPU performance without having to worry about VL-
