, respectively. The peripheral function modes
of these pins are selected by bits 0–2 (PMRB0–PMRB2) of port mode register B (PMRB: $024) (figure

are multiplexed with peripheral pins TOB, TOC, and TOD, respectively. The peripheral
function modes of these pins are selected by bits 0 and 1 (TMB20, TMB21) of timer mode register B2
(TMB2: $013), bits 0–2 (TMC20–TMC22) of timer mode register C2 (TMC2: $014), and bits 0–3
(TMD20–TMD23) of timer mode register D2 (TMD2: $015) (figures 32, 31, and 33).

are multiplexed with peripheral pins
EVNB
and EVND, respectively. The peripheral
function modes of these pins are selected by bits 0 and 1 (PMRC0, PMRC1) of port mode register C
(PMRC: $025) (figure 34).
Pins R2

are multiplexed with peripheral pins
SCK
, SI, and SO, respectively. The peripheral function
modes of these pins are selected by bit 3 (SMRA3) of serial mode register A (SMRA: $005), and bits 0 and
1 (PMRA0, PMRA1) of port mode register A (PMRA: $004), as shown in figures 35 and 36.
Ports R6 and R7 are multiplexed with segment pins SEG13–SEG20, respectively. The function modes of
these pins can be selected in 4-pin units by setting LCD output register 3 (LOR3: $01F) (figure 37).
