Waveform Generator Phase 1
Complementary 3-phase output signals used in motion-
control applications.
Write. This active-low output indicates that an external write
is occurring. This signal is asserted only during external
memory writes.
Write High. During 16-bit bus cycles, this active-low output
signal is asserted for high-byte writes and word writes to
external memory.
During 8-bit bus cycles, WRH# is asserted for all write
operations.
Write Low. During 16-bit bus cycles, this active-low output
signal is asserted for low-byte writes and word writes.
During 8-bit bus cycles, WRL# is asserted for all write
operations.
Clock/Oscillator Input. Input to the on-chip oscillator
inverter and the internal clock generator. Also provides the
clock input for the serial I/O baud-rate generator, timers, and
PWM unit. If an external oscillator is used, connect the
external clock input signal to XTAL1 and ensure that the

Oscillator Output. Output of the on-chip oscillator inverter.
When using the on-chip oscillator, connect XTAL2 to an
external crystal or resonator. When using an external clock
source, let XTAL2 float.
