322
CountUpFlag
Data type
BOOL
Used with all of the HSCs (modes 0...9). If the HSCSTS.CountEnable bit is set,
the Count Up bit is set (1). If the HSCSTS.CountEnable is cleared, the Count
Up bit is cleared (0).
CountDownFlag
Data type
BOOL
Used with the bidirectional counters (modes 2...9). If the HSCSTS.CountEnable
bit is set, the Count Down bit is set (1). If the HSCSTS.CountEnable bit is clear,
the Count Down bit is cleared (0).
Mode1Done
Data type
BOOL
The HSC sub-system sets the HSCSTS.Mode1Done status flag to (1) when the
HSC is configured for Mode 0 or Mode 1 behavior, and the accumulator counts
up to the High Preset value.
OVF
Data type
BOOL
The HSC sub-system sets the HSCSTS.OVF status flag to (1) whenever the
accumulated value (HSCSTS.Accumulator) has counted through the overflow
variable (HSCAPP.OFSetting). This bit is transitional and is set by the HSC sub-
system. It is up to the control program to use, track, and clear (0) the overflow
condition.
Overflow conditions do not generate a controller fault.
