SSI mode 1:
Timer 2 output mode 2:
Timer 2 output mode 1/6:
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 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 programmed to generate the two frequen-
cies 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.
