Integrated Power-On Reset
An internal Power-On Reset generator is integrated. When The supply voltage ramps up, the
internal reset signal is kept active (low) for about 24 us typical. To activate this function the
RESETB must be left unconnected.

Oscillator circuitry
The internal oscillator cell requires an external quartz or an external oscillator respectively
(Figure 5, Figure 6). The internal controller clock is available at the port MICROTICK (inverted
to clock signal applied at XOUT0).

Table 5: TTP/C Bus Interface Ports
The controller can be connected to transceivers with recessive state and to transceivers with
three-state outputs, respectively. For safe operation of the device the bus driver enable signal
BDE must be connected with output enable OE. To deactivate the bus guardian the OE signal
has to be tied to VCC. Applications with recessive state transceivers do not use the CTS
signal.
