USER’S MANUAL
The CSx timing is defined by the setup time required between the address lines and
the CE line. The memory controller allows the user to specify the CS timing to meet
the setup time required by the peripheral device. This is accomplished through the
ACS field in the base register. In
asserted half a clock cycle after the address lines are valid.
