SSI mode 1:
Timer 2 output mode 2:
Timer 2 output mode 1/6: Timer 2 compare match toggles (TOG2) to the SSI
Timer 3 mode 7:
The Timer 3 counter is driven by an internal or external clock source. Its compare- and
compare mode registers must be programmed to generate the carrier frequency with
the output toggle flip-flop (M3). The internal data output (SO) of the SSI is used to
enable and disable the Timer 3 output. The SSI can be supplied with the toggle signal of
Timer 2.
SSI mode 1:
Timer 2 output mode 3:
Timer 2 output mode 1/6: Timer 2 4-bit compare match signal (POUT) to the SSI
Timer 3 mode 8:
The two compare registers are used to generate two different 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 pro-
grammed to generate the two frequencies via the output toggle flip-flop. 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.
