Description
Port 0
8-bit bi-directional I/O
port with separated
inputs and outputs
Port 1
8-bit bi-directional I/O
port with separated
inputs and outputs
Port 2
8-bit bi-directional I/O
port with separated
inputs and outputs
Port 3
8-bit bi-directional I/O
port with separated
inputs and outputs
Clock
A pulse for internal
clock counters and all
synchronous circuits
Hardware reset
Resets the device
when this pin is held
high for two clock
cycles while the
oscillator is running
Engine clock
A pulse for internal
circuits that are
stopped when the
R80515 is in the IDLE
or STOP mode
Engine clock output
Is the gated clk clock.
clkcpuo stays low
when the R80515
enters into IDLE or
STOP mode. The
clkcpuo is dedicated
to off-core connection
to the clkcpu input
Peripheral clock
A pulse for internal
circuits that are
stopped when the
R80515 is in STOP
mode
Peripheral clock
output is the gated
clk clock. clkpero stays
low when the R80515
enters into STOP
mode. The clkpero is
dedicated to off-core
connection to the
clkper input
