I/O Port Sink Current Selection - Holtek BS86DH12C Manual

I/O Port Sink Current Selection

The device supports different output sink current driving capability for each I/O port. With the
selection register, SLEDCOMn, specific I/O port can support two levels of the sink current driving
capability. These sink current selection bits are available when the corresponding pin is configured
as a CMOS output. Otherwise, these select bits have no effect. Users should refer to the Input/Output
Characteristics section to select the desired output sink current for different applications.
