#HSO? 80C19? 131#
Determine which HSO interrupts you want to enable.

The HSO module can generate two different interrupts: the High-Speed Output
interrupt (INT03) and the Software Timer interrupt (INT05).  External events
generate the High-Speed Output interrupt, if the interrupt is enabled
(INT_MASK.3 set).  Internal events generate the Software Timer interrupt, if
the interrupt is enabled (INT_MASK.5 set).
#HSO? 80C196KC 160#
#HSO? 80C196KD 160#
Select an HSO event.

The HSO can trigger fifteen different events, which are classified as
external or internal.  The external events are those that toggle one or more
of the HSO outputs; the internal events are those that set up the software
timers, reset Timer 2, and start an A/D conversion.  All of these events set
flags that can optionally generate interrupts.

In general, external events generate the High-Speed Output interrupt (INT03)
and internal events generate the Software Timer interrupt (INT05). The HSO_ALL
event is an exception. Although it is defined as an external event, HSO_ALL
generates the Software Timer interrupt (INT05). 

When a Software Timer interrupt occurs, the interrupt service routine can
check IOS1 and IOS2 to determine the source of the interrupt. A software
timer event sets the corresponding bit in IOS1. A Timer 2 reset or an A/D
conversion start sets the corresponding bit in IOS2, and an HSO_ALL event
sets six bits (IOS2.0 - IOS2.5).
#HSO? 80C196KB 160#
#HSO? 80C198 160#
Select an HSO event.

The HSO can trigger fourteen different events, which are classified as
external or internal.  The external events are those that toggle one or more
of the HSO outputs; the internal events are those that set up the software
timers, reset Timer 2, and start an A/D conversion.  All of these events set
flags that can optionally generate interrupts.
#HSO? 80C194 160#
Select an HSO event.

interrupts.

predefined times.  At the specified time, the HSO sets a flag in the IOS1
register; if the interrupt is enabled, it also generates a Software Timer
interrupt.  If more than one software timer expires within the same time
frame, multiple status bits are set.  The Interrupt service routine can
examine the IOS1 register to determine which software timer(s) caused the
interrupt.

the HSO unit to trigger an A/D conversion, the conversion parameters must be
set up in the A/D control registers, and the conversion source bit
(AD_COMMAND.3) must be cleared to specify that the HSO is to initiate the
conversion.

When a command is locked in the CAM, the command remains in the CAM after
execution.  This feature makes it easy to generate periodic events or
waveforms.  When CAM locking is disabled, the command is cleared from the CAM
after execution.
