BUS INTERFACE UNIT SUBMODULE (BIUSM)
2.1
BIUSM description
The BIUSM connects the CTM’s SMB to the IMB and allows the CTM submodules to communicate
with the bus master (usually a CPU). The BIUSM also communicates interrupt requests, from the
CTM submodules to the IMB, and transfers the interrupt level, arbitration bit and vector number to
the CPU during the interrupt acknowledge cycle. The BIUSM contains a module configuration
register, a time base bus register and a test register (for factory testing only).
2.2
Freeze action on the BIUSM
When the IMB freeze condition is detected, the FRZ bit in the BIUSM module configuration register
determines whether or not the freeze condition is passed on to the other CTM submodules. If FRZ
= 0, the freeze condition is ignored; if FRZ = 1, the BIUSM passes the FREEZE signal from the
IMB through to the CTM submodules. Each CTM submodule then reacts to the FREEZE signal as
defined by its own internal circuitry and control bits.
2.3
LPSTOP action on the BIUSM
When the CPU is stopped by an LPSTOP instruction (from CPU32 or CPU16), the system clock
(f
SYS
) is stopped, thereby shutting down all dependent modules, including the CTM, until the
low-power STOP mode is exited.
