Both TWD and TWCK are bidirectional lines, connected to a positive supply voltage via a current
source or pull-up resistor (see
high. The output stages of devices connected to the bus must have an open-drain or open-col-
lector to perform the wired-AND function.
TWD and TWCK pins may be multiplexed with GPIO lines. To enable the TWI, the programmer
must perform the following steps:
• Program the GPIO controller to:
The TWI clock is generated by the Power Manager (PM). Before using the TWI, the programmer
must ensure that the TWI clock is enabled in the PM.
In the TWI description, Master Clock (MCK) is the clock of the peripheral bus to which the TWI is
connected.

– Dedicate TWD and TWCK as peripheral lines.
– Define TWD and TWCK as open-drain.
