PIC18F87K90 FAMILY
11.1.3
The output pins for several peripherals are also
equipped with a configurable, open-drain output option.
This allows the peripherals to communicate with
external digital logic, operating at a higher voltage
level, without the use of level translators.
The open-drain option is implemented on port pins
specifically associated with the data and clock outputs
of the USARTs, the MSSP module (in SPI mode) and
the CCP modules. This option is selectively enabled by
setting the open-drain control bits in the registers:
ODCON1, ODCON2 and ODCON3.
When the open-drain option is required, the output pin
must also be tied through an external pull-up resistor
provided by the user to a higher voltage level, up to 5V
(Figure
