STROBE – Strobe Register
DATA – Data Register
Table 6-6.
• Bit 7:4 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 3:0 – STROBE[3:0]: Strobe Register
If the STROBE register location is written, each event channel will be set according to the
STROBE[n] and corresponding DATA[n] bit settings, if any are unequal to zero.
A single event lasting for one peripheral clock cycle will be generated.
• Bit 7:4 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 7:0 – DATA[7:0]: Data Register
This register contains the data value when manually generating a data event. This register must
be written before the STROBE register. For details,
