##### Possible improvement
|
||||||
|
|
||||||
|
`SH/LD` is always pulled low at the same time as `CLK INH` is pulled high. That
|
||||||
|
means `CLK INH` could be driven from the same pin as `SH/LD` using a
|
||||||
|
single-transistor NOT gate. This would free another pin for an extra LED or
|
||||||
|
something.
