PIC16F1829LIN
5.0 I/O PORTS
5.1 Alternate Pin Function
The Alternate Pin Function Control 0 (APFCON0) and
Alternate Pin Function Control 1 (APFCON1) registers
are used to steer specific peripheral input and output
functions between different pins. It functions the same
as described in the “PIC16(L)F1825/1829 Data Sheet”
(DS41440) with the differences described below.
The APFCON0 and APFCON1 registers are shown in
Register 5-1 and Register 5-2. For this device family,
the following functions can be moved between different
pins.
• RX/DT/TX/CK
• T1G
• P1B/P1C/P1D/P2B
• CCP1/P1A/CCP2
These bits have no effect on the values of any TRIS
register. PORT and TRIS overrides will be routed to the
correct pin. The unselected pin will be unaffected.
