Pin Functions and Selection Method
Bit PWM0 in TMDR, bits IOB2 to IOB0 in TIOR0, bits TPSC2 to TPSC0 in
16TCR2 to 16TCR0 of the 16-bit timer, bits CKS2 to CKS0 in 8TCR2 of the 8-bit
timer, bit NDER3 in NDERA, and bit PA3DDR select the pin function as follows.

Notes: 1. TIOCB0 input when IOB2 = 1 and PWM0 = 0.
2. TCLKD input when TPSC2 = TPSC1 = TPSC0 = 1 in any of 16TCR2
to 16TCR0, or bits CKS2 to CKS0 in 8TCR2 are as shown in (3) in the
table below.
