Combination Timer 3 and SSI
Combination Mode 6:
FSK Modulation
SSI mode 1:
8-bit shift register internal data output (SO) to the Timer 3
Timer 3 mode 8: FSK modulation with shift register data (SO)
The two compare registers are used to generate two varied time intervals. The SSI data
output selects which compare register is used for the output frequency generation. A "0"
level at the SSI data output enables the compare register 1 and a "1" level enables the
compare register 2. The compare and compare mode registers must be programmed to
generate the two frequencies via the output toggle flip-lop. The SSI can be supplied with
the toggle signal of Timer 2 or any other clock source. The Timer 3 counter is driven by
an internal or external clock source.
