5.5 MC68HC05C9A Compatible COP
This COP is controlled with two registers; one to reset the COP timer and the other to enable and control
COP and clock monitor functions. Figure 5-3 shows a block diagram of the MC68HC05C9A COP.
Figure 5-3. C9A COP Block Diagram
5.5.1 C9A COP Reset Register
This write-only register, shown in Figure 5-4, is used to reset the COP.
The sequence required to reset the COP timer is:
Write $55 to the COP reset register
Write $AA to the COP reset register
Both write operations must occur in the order listed, but any number of instructions may be executed
between the two write operations provided that the COP does not time out between the two writes. The
elapsed time between software resets must not be greater than the COP timeout period. If the COP
should time out, a system reset will occur and the device will be re-initialized in the same fashion as a
power-on reset or reset.
Reading this register does not return valid data.
5.5.2 C9A COP Control Register
The COP control register, shown in Figure 5-5, performs these functions:
Enables clock monitor function
Enables MC68HC05C9A compatible COP function
Selects timeout duration of COP timer
and flags the following conditions:
A COP timeout
Clock monitor reset
