I/O Lines Description
Figure 38-2. Application Block Diagram
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 PIO lines. To enable the TWI, the programmer
must perform the following step:
The user must not program TWD and TWCK as open-drain. It is already done by the hardware.
The TWI interface may be clocked through the Power Management Controller (PMC), thus the
programmer must first configure the PMC to enable the TWI clock.
• Program the PIO controller to dedicate TWD and TWCK as peripheral lines.
• Enable the peripheral clock.
