RX210 Group 1. Overview
1.4 Pin Functions
Table 1.8 lists the pin functions.
Table 1.8 Pin Functions (1 / 4)
Classifications Pin Name I/O Description
Power supply VCC Input Power supply pin. Connect it to the system power supply.
VCL — Connect this pin to the VSS pin via the 0.1 μF smoothing capacitor
used to stabilize the internal power supply. Place the capacitor close
to the pin.
VSS Input Ground pin. Connect it to the system power supply (0 V).
Clock XTAL Output Pins for connecting a crystal resonator. An external clock signal can
be input through the EXTAL pin.
EXTAL Input
BCLK Output Outputs the external bus clock for external devices.
XCIN Input Input/output pins for the sub-clock oscillator. Connect a crystal
resonator between XCIN and XCOUT.
XCOUT Output
Operating mode
control
MD Input Pin for setting the operating mode. The signal levels on this pin
must not be changed during operation.
System control RES# Input Reset pin. This LSI enters the reset state when this signal goes low.
CAC CACREF Input Input pin for the measuring circuit for clock frequency precision.
On-chip emulator FINED I/O FINE interface pin.
Address bus A0 to A23 Output Output pins for the address.
Data bus D0 to D15 I/O Input and output pins for the bidirectional data bus.
Multiplexed bus A0/D0 to A15/D15 I/O Address/data multiplexed bus
Bus control RD# Output Strobe signal which indicates that reading from the external bus
interface space is in progress.
WR# Output Strobe signal which indicates that writing to the external bus
interface space is in progress, in single-write strobe mode.
WR0#, WR1# Output Strobe signals which indicate that either group of data bus pins (D7
to D0, and D15 to D8) is valid in writing to the external bus interface
space, in byte strobe mode.
BC0#, BC1# Output Strobe signals which indicate that either group of data bus pins (D7
to D0 and D15 to D8) is valid in access to the external bus interface
space, in single-write strobe mode.
CS0# to CS3# Output Select signals for areas 0 to 3.
WAIT# Input Input pin for wait request signals in access to the external space.
ALE Output Address latch signal when address/data multiplexed bus is
selected.
Interrupt NMI Input Non-maskable interrupt request pin.
IRQ0 to IRQ7 Input Interrupt request pins.
