Timing was designed for a system load between 5pF and 40pF
Clock jitter on the SSPSCLK is designed to be an average of the specified clock frequency. The
SSPSCLK jitter specification is unspecified.
Minimum and maximum clock periods which can
be produced by the SSP_SCLK when the clock is
being generated from the internal 3.7033MHz
clock.
Minimum and maximum clock period which can be
produced by the SSP_SCLK when the clock is being
generated from the externally supplied maximum
clock rate of 33 MHz clock (SSP_EXTCLK).
Input Setup time for data prior to the valid edge of
SSP_SCLK. These signals include SSP_SRXD.
Input hold time for data after the to the valid edge
of SSP_SCLK. These signals include SSP_SRXD.
SSP_SCLK clock to output valid delay from output
signals. These signals include SSP_STXD and
SSP_SFRM.
Output data hold valid from valid edge of
SSP_SCLK. These signals include SSP_STXD and
SSP_SFRM.
Output Valid Delay from SSP_EXTCLK to SSP_SCLK
in external clock mode
