USER’S MANUAL
This section is an overview of CTM4 function. Refer to the CTM Reference Manual
(CTMRM/AD) for a comprehensive discussion of CTM capabilities.
The configurable timer module 4 (CTM4) consists of several submodules which are lo-
cated on either side of the CTM4 internal submodule bus (SMB). All data and control
signals within the CTM4 are passed over this bus. The SMB is connected to the out-
side world via the bus interface unit submodule (BIUSM), which is connected to the
intermodule bus (IMB), and subsequently the CPU32. This configuration allows the
CPU32 to access the data and control registers in each CTM4 submodule on the SMB.
Three time base buses (TBB1, TBB2 and TBB4), each 16-bits wide, are used to trans-
fer timing information from counters to action submodules. Figure 10-1 shows a block
diagram of the CTM4.
