MC68336/376
USER’S MANUAL
ator, though internally, channel B has two data registers (B1 and B2). DASM operating
mode determines which register is software accessible. Refer to Table 10-3.
Register contents are always transferred automatically at the correct time so that the
minimum pulse (measured or generated) is just one time base bus count. The A and
B data registers are always read/write registers, accessible via the CTM4 submodule
bus.
The CTM4 has four DASMs. Figure 10-5 shows a block diagram of the DASM.

REGISTER B
MODE1 MODE0
Registers A and B2 are used to hold the captured values. In these modes,
the B1 register is used as a temporary latch for channel B.
Registers A and B2 are used to define the output pulse. Register B1 is not
used in these modes.
Registers A and B1 are used as primary registers and hidden register B2 is
used as a double buffer for channel B.
