• Manufacturer Part Number: SAF-C164SM
• Description: 16-Bit CMOS Microcontroller
• Manufacturer: Infineon Technologies

The three 16-bit capture/compare channels are driven via timer T12 and each can
control two output lines (see Port Control Logic). The offset register T12OF (full function
module only) allows shifting of the switching points of the COUT6x output line of each
channel by shifting the respective compare value.
The 10-bit compare channel is driven via timer T13 and can control one output line.
Additional control logic allows the capture/compare channel outputs to be combined with
the compare channel output or with external signals. Thus flexible and complex output
patterns can be generated automatically, with very little or no CPU action.

Two basic operating modes are supported:
• Edge-Aligned Mode
• Center-Aligned Mode
In Edge Aligned Mode the compare timer counts up starting at 0000
the period value stored in register TxP the timer is cleared and repeats counting up. At
this time the output signals are also switched to their passive state. Edge aligned mode
is supported by both compare timers, T12 and T13.
