OC:
Output Compare (Timer Function)
The output compare (OC) mechanism of a timer can be used to schedule an
output change to occur at a specific time in a timer cycle. The planned
output change occurs when the free-running counter matches the value in
the output compare register. This is the timer mechanism typically used
for control of outgoing timing references.
OSD:
On-Screen Display
The on-screen display (OSD) module converts programmed character addresses
and control information into digital color and blanking outputs to display
user defined characters on a television screen for on-screen programming
and closed-captioning applications.
OTPROM:
One Time Programmable Read Only Memory
One-time Programmable Read Only Memory (OTPROM) is an EPROM that does not
have a window on top of the package, which means that the memory cannot be
exposed to ultraviolet light and therefore cannot be erased and
reprogrammed. OTPROM versions of most microcontrollers are available to
support your development and production needs. OTP information is
non-volatile in that it does not change when power is removed.
