R Port
The R port consists of 10 I/O pins that are addressed in 4-bit units.
Input can be performed by means of the LAR and LBR instructions, and output by means of the LRA and
LRB instructions. Output data is stored in the port data register (PDR) for each pin.
The R port output buffer is turned on and off by the R port data control registers (DCR0 to DCR2, DCR7:
$034 to $036, $03B). The DCR registers are mapped onto memory addresses (figure 25).
Port R0
0
is multiplexed as wakeup input pin
WU
0
. Setting of this pin as peripheral function pins is
performed by port mode register 1 (PMR1: $009) (figure 27).
Port R1
0
is multiplexed as peripheral function pin EVNB. Setting of this pin as peripheral function pins is
performed by bit 0 (PMR20) of port mode register 2 (PMR2: $00A) (figure 28).
Ports R1
3
and R2
0
are multiplexed as peripheral function pins TOB, and TOC, respectively. Setting of
these pins as peripheral function pins is performed by bits 3 (PMR23) of port mode register 2 (PMR2:
$00A) and bit 0 (PMR30) of port mode register 3 (PMR3: $00B)(figures 28 and 29).
Ports R2
1
and R2
2
are multiplexed as peripheral function pins
SCK
and SI/SO, respectively. Setting of
these pins as peripheral function pins is performed by bits 1 to 3 (PMR31 to PMR33) of port mode register
3 (PMR3: $00B) (figure 29).
Ports R7
0
to R7
3
are multiplexed as peripheral function pins AN
0
to AN
3
(HD404374, HD404384, and
HD404389 Series only). Setting of these pins as peripheral function pins is performed by bits 1 to 3
(AMR1 to AMR3) of the A/D mode register (AMR: $028) (see figure 64 in section 8, A/D Converter).
