Programmable IO Delays
DDR-SDRAM Controller (DDRSDRC) User Interface
AT91SAM9M10
SMC
The external bus interface consists of a data bus, an address bus and control signals. The simul-
taneous switching outputs on these busses may lead to a peak of current in the internal and
external power supply lines.
In order to reduce the peak of current in such cases, additional propagation delays can be
a d j u s t e d i n d e p e n d e n t l y f o r p a d b u f f e r s b y m e a n s o f c o n f i g u r a t i o n r e g i s t e r s ,
DDRSDRC_DELAY1-8.
The additional programmable delays for each IO range from 0 to
delay can differ between IOs supporting this feature. Delay can be modified per programming for
each IO. The minimal additional delay that can be programmed on a PAD supporting this feature
is 1/16 of the maximum programmable delay.
When programming 0x0 in fields “Delay1 to Delay8”, no delay is added (reset value) and the
propagation delay of the pad buffers is the inherent delay of the pad buffer. When programming
0xF in field “Delay1” the propagation delay of the corresponding pad is maximal.
