When using ICs that use enable pins, what is the best practice for driving them in a microcontroller system (particularly when there's no especially pressing need to disable the device at any time)?
For example, I'm using a chain of parallel-to-serial shift registers to aggregate a large number of physical device inputs into a single serial bitstream to my uC, and these registers only operate when a
clk_en clock enable pin is driven low.
The inputs will be polled for the lifetime of the uC, so at no point do I NEED to explicitly disable the
Is it considered bad practice to have this pin permanently pulled low (i.e. with a pull-down resistor)?
