time the 16-bit counter will reset to zero and begin
counting until the inactive timer expires. The cadence
continues until the user clears the O1TAE and O1TIE
control bits. The zero crossing detect feature can be
implemented by setting the OZ1 bit (direct Register 32,
bit 5). This ensures that each oscillator pulse ends
without a dc component. The timing diagram in
Figure 21 is an example of an output cadence using the
zero crossing feature.
One-shot oscillation can be achieved by enabling O1E
and O1TAE. Direct control over the cadence can be
achieved by controlling the O1E bit (direct Register 32,
bit 2) directly if O1TAE and O1TIE are disabled.

The operation of tone generator 2 is identical to that of
tone generator 1 using its respective control registers.
Note: Tone Generator 2 should not be enabled simultane-
Continuous
waveforms may be created using tone generator 1 (not
available on tone generator 2) by setting the REL bit
(direct Register 32, bit 6), which enables reloading of
the OSC1, OSC1X, and OSC1Y registers at the
expiration of the active timer, OAT1.
