18.0
PIC18F4455/4550 USB devices provide a Streaming
Parallel Port as a high-speed interface for moving data
to and from an external system. This parallel port
operates as a master port, complete with chip select
and clock outputs to control the movement of data to
slave devices. Data can be channelled either directly to
the USB SIE or to the microprocessor core. Figure 18-1
shows a block view of the SPP data path.

In addition, the SPP can provide time multiplexed
addressing information along with the data by using the
second strobe output. Thus, the USB endpoint number
can be written in conjunction with the data for that
endpoint.
18.1
The operation of the SPP is controlled by two registers:
SPPCON and SPPCFG. The SPPCON register
(Register 18-1) controls the overall operation of the
parallel port and determines if it operates under USB or
microcontroller
(Register 18-2) controls timing configuration and pin
outputs.
18.1.1
To enable the SPP, set the SPPEN bit (SPPCON<0>).
In addition, the TRIS bits for the corresponding SPP
pins must be properly configured. At a minimum:
• Bits TRISD<7:0> must be set (= 1)
• Bits TRISE<2:1> must be cleared (= 0)
If CK1SPP is to be used:
• Bit TRISE<0> must be cleared (= 0)
If CSPP is to be used:
• Bit TRISB<4> must be cleared (= 0)
