16.3.1.1 IP Bus Interface
The Bluetooth core interfaces to the IP 2.0 bus. The IP bus clock (ips_cont_clk) ranges from 24 MHz to
100 MHz. Running the clock outside of these ranges will cause the interface to fail due to internal
synchronization logic.
The IP bus clock is faster than, and out of phase with, the internal 8 MHz clock. The Bluetooth module
inserts dynamic wait states to synchronize the IP bus clock with this internal clock. Table 16-1 shows the
recommended settings for inserting dynamic wait-states into the internal read and write cycles (by using
the ips_xfr_wait signal) to complete the read/write cycle. Refer to Section 16.5.9.1, “Clock Control
Register.”
