D.7.1 BIU Module Configuration Register

USER’S MANUAL
STOP

0
RESET:
When the STOP bit is set, the clock to the CTM4 is shutdown, placing the module into
low-power stop mode. The BIUSM still operates in low-power stop mode, allowing the
submodule control and data registers to be accessed.
The FRZ bit controls CTM4 response to assertion of the IMB FREEZE signal. Since
the BIUSM propagates FREEZE to the CTM4 submodules via the submodule bus, the
setting of FRZ affects all CTM4 submodules.
This bit field selects the base interrupt vector number for the CTM4. Of the eight bits
necessary for a vector number, the six low-order bits are hardware defined on a sub-
module basis, while the two remaining bits are provided by VECT[7:6]. This places the
CTM4 vectors in one of four possible positions in the interrupt vector table. Refer to
Table D-36.
0 = Enable CTM4 clocks.
1 = Disable CTM4 clocks.
0 = CTM4 ignores the IMB FREEZE signal.
1 = CTM4 submodules freeze when the IMB FREEZE signal is asserted.
