Write Low
During 16-bit bus cycles, this active-low output signal is asserted for low-byte writes
and word writes to external memory. During 8-bit bus cycles, WRL# is asserted for
all write operations.
WRL# with WR#.
† The chip configuration register 0 (CCR0) determines whether this pin functions as
Input Crystal/Resonator or External Clock Input
Input to the on-chip oscillator and the internal clock generators. The internal clock
generators provide the peripheral clocks, CPU clock, and CLKOUT signal. When
using an external clock source instead of the on-chip oscillator, connect the clock
input to XTAL1. The external clock signal must meet the V
Inverted Output for the Crystal/Resonator
Output of the on-chip oscillator inverter. Leave XTAL2 floating when the design uses
an external clock source instead of the on-chip oscillator.
WR# or WRL#. CCR0.2 = 1 selects WR#; CCR0.2 = 0 selects WRL#.
