• T5 – Port L, Bit 2
T5, Timer/Counter5 counter source.
• ICP5 – Port L, Bit 1
ICP5, Input Capture Pin 5: The PL1 pin can serve as an Input Capture pin for Timer/Counter5.
• ICP4 – Port L, Bit 0
ICP4, Input Capture Pin 4: The PL0 pin can serve as an Input Capture pin for Timer/Counter4.
Table 13-34 and Table 13-35 relates the alternate functions of Port L to the overriding signals
shown in Figure 13-5 on page 76.
