11.9 Bus Driver Protection
11.9 Bus Driver Protection
• One method to protect the device against latch-up due to collision of the bus drivers is the use of an open-
• When using the SEI pins as CMOS outputs, we recommend connecting them to the bus via resistors in order
drain option. This means changing the SEI pins’ CMOS outputs to the open-drain type, which is accom-
plished by setting the SCLK, MOSI, and MISO pins for open-drain individually by using the each Port
Input/output Control Register. In this case, these pins must be provided with pull-up resistors external to the
chip.
to protect the device against collision of drivers. However, be sure to select the appropriate resistance value
which will not affect actual device operation (Example: 1 Ω to several kΩ).
