General advice on how to read a datasheet (I am updating this as I go)
|
|
|
|
## Digital pins
|
|
|
|
### Inverted/Active low/NOT
|
|
|
|
A pin which is active low is typically designated with a `/` or an overbar
|
|
|
|
For example: /CS or <span style="text-decoration:overline">CS</span>
|
|
|
|
A common example is the chip select (/CS) pin on devices with SPI, where the chip select must be low for the SPI on the chip to become active. When it it high, it is idle.
