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 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.
TWALM is used to implement the optional SMBus SMBALERT signal.
The TWALM, TWD, and TWCK pins may be multiplexed with I/O Controller lines. To enable the
TWIM, the programmer must perform the following steps:
If the CPU enters a sleep mode that disables clocks used by the TWIM, the TWIM will stop func-
tioning and resume operation after the system wakes up from sleep mode.
• Program the I/O Controller to:
Rp: Pull up value as given by the I²C Standard
Master
– Dedicate TWD, TWCK and optionally TWALM as peripheral lines.
– Define TWD, TWCK and optionally TWALM as open-drain.
