NOTE
All of the functions associated with one pin are called a SASM channel.
The SASM can perform a single timing action (input capture or output compare) before software inter-
vention is required. Each channel includes a 16-bit comparator and one 16-bit register for saving an in-
put capture value or for holding an output compare value. The input edge detector associated with each
pin is programmable to cause the capture function to occur on the rising or falling edge. The output flip
flop can be set to either toggle when an output compare occurs or to transfer a software-provided bit
value to the output pin. In either input capture or output compare mode, each channel can be pro-
grammed to generate an interrupt. One of the two incoming time-base buses may be selected for each
channel. Each channel can also work as a simple I/O pin.
A total of four SASMs (eight channels) are contained in the CTM6.
Figure 22
shows a block diagram
of the SASM.

6.9.1 SASM Registers
The SASM contains two status/interrupt/control registers (A and B) and two data registers (A and B).
All unused bits and reserved address locations return zero when read. Writing to unused bits and
reserved address locations has no effect. The CTM6 contains four SASMs, each with its own set of reg-
isters.
