3). During Matrix Scanning
a). A key is released while one of the drivers outputs is in the low ohmic state (Logic 0)
b). A key is released before that key has been detected.
c). There is no wired connection in the C-KO Matrix when SMS is in High State.
7. OSCILLATOR
The OSC is a 1-pin oscillator input/output terminal. The oscillator is constructed by connecting in series a
ceramic resonator like TOKO CRK429.
8. TEST MODE
When T1, T2 and OSC Pins are in HIGH State, the circuit initializes. All internal nodes except for the LATCH
are defined. The latch is defined when a scan cycle starts by pulling down a KI or a C Input while the oscillator is
active.
If the debounce cycle has been completed, then the scan cycle can be accomplished 3x23 times faster by
setting the T1 to HIGH. If the scan cycle has been completed, the Latch contents can be read 3x27 times faster
by setting the T2 to HIGH.
