– Null Pulse
– Read is Controlled by NRD (READ_MODE = 1):
Read Mode
Figure 27-10. No Setup, No Hold On NRD and NCS Read Signals
Programming null pulse is not permitted. Pulse must be at least set to 1. A null value leads to
unpredictable behavior.
As NCS and NRD waveforms are defined independently of one other, the SMC needs to know
when the read data is available on the data bus. The SMC does not compare NCS and NRD tim-
ings to know which signal rises first. The READ_MODE parameter in the MODE register of the
corresponding chip select indicates which signal of NRD and NCS controls the read operation.
Figure 27-11
read data is available t
NRD. In this case, the READ_MODE must be set to 1 (read is controlled by NRD), to indicate
that data is available with the rising edge of NRD. The SMC samples the read data internally on
the rising edge of Master Clock that generates the rising edge of NRD, whatever the pro-
grammed waveform of NCS may be.
