In order to use this module, other parts of the system must be configured correctly, as
described below.
Both TWD and TWCK are bidirectional lines, connected to a positive supply voltage via a cur-
rent source or pull-up resistor (see
are high. The output stages of devices connected to the bus must have an open-drain or open-
collector to perform the wired-AND function.
TWALM is used to implement the optional SMBus SMBALERT signal.
TWALM, TWD, and TWCK pins may be multiplexed with I/O Controller lines. To enable the
TWIS, the programmer must perform the following steps:
• Program the I/O Controller to:
