SPKR See Section 9.4.3 for more information.
Strap function: No Reboot (See the
6300ESB EDS for more information)
Has integrated pull-down. The integrated
pull-down is only enabled at boot/reset for
strapping functions; at all other times, the
pull-down is disabled.

No extra series termination
resistors or other pull-ups/pull-
downs are required.
PDD7/SDD7 does not require a

These signals have
integrated series resistors.
NOTE: Simulation data
indicates that the
integrated series
termination
resistors are a
nominal 33
Ω but
may range from
21
Ω to 75 Ω.
