CTSx—Clear To Send 2 and 3
USBRXN—USB Receive (Negative Differential)
USBRXP—USB Receive (Positive Differential)
DREQx— DMA Request to the RISC Microcontroller
0 = PCx is a general-purpose interrupt I/O pin. The SCCx internal CTSx signal is
1 = PCx is connected to the corresponding SCCx signal input in addition to being a
0 = PC10 is general purpose I/O pin. If PCDIR configures this pin as an input, the pin
1 = PC10 functions as USBRXN, provided that bits PCDIR[10] and PCPAR[10] are
0 = PC11 is general purpose I/O pin. If PCDIR configures this pin as an input, the pin
1 = PC11 functions as USBRXP, provided that bits PCDIR[11] and PCPAR[11] are
0 = PCx is a general-purpose interrupt I/O pin, with the direction controlled in PCDIR.
1 = PCx becomes an external request to the RISC microcontroller instead of being a
always asserted. If PCDIR configures this pin as an input, the pin can generate an
interrupt to the core, as controlled by the PCINT bits.
