ATtiny261/461/861

Table 12-4 and Table 12-5 relate the alternate functions of Port B to the overriding signals

shown in Figure 12-5 on page 59.

Note: 1. 1 when the Fuse is “0” (Programmed).

Note: 1. INTRC means that one of the internal RC Oscillators are selected (by the CKSEL fuses),

EXTCK means that external clock is selected (by the CKSEL fuses).
