20-bit programmable counter plus 12-bit interval counter
12-bit key-protected Programmable Counter running on prescaled SLCK
Provides reset or interrupt signals to the system
Counter may be stopped while the processor is in debug state or in idle mode
32-bit free-running counter with alarm running on prescaled SLCK
Programmable 16-bit prescaler for SLCK accuracy compensation
One PIO Controller, controlling 21 I/O lines
Fully programmable through set/clear registers
Multiplexing of two peripheral functions per I/O line
For each I/O line (whether assigned to a peripheral or used as general-purpose I/O)
