CTRLGCLR/CTRLGSET - Control Register G Clear/Set
• Bit 3:2 - CMD[1:0]: Timer/Counter Command
These command bits can be used for software control of update, restart, and reset of the
Timer/Counter. The command bits are always read as zero.
Table 14-7.
• Bit 1 - LUPD: Lock Update:
When this bit is set no update of the buffered registers is performed, even though an UPDATE
condition has occurred. Locking the update ensures that all buffers, including DTI buffers, are
valid before an update is performed.
This bit has no effect when input capture operation is enabled.
• Bit 0 - DIR: Counter Direction:
When zero, this bit indicates that the counter is counting up (incrementing). A one indicates that
the counter is in down counting (decrementing) state.
Normally this bit is controlled in hardware by the waveform generation mode, or by event
actions, but this bit can also be changed from software.
Refer to section
mation on how to access this type of status register.
• Bit 7:5 - 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 4:1 - CCxBV: Compare or Capture x Buffer Valid
These bits are set when a new value is written to the corresponding CCxBUF register. These
bits are automatically cleared on an UPDATE condition.
Note that when input capture operation is used, this bit is set on capture event and cleared if the
corresponding CCxIF is cleared.
• Bit 0 - PERBV: Period Buffer Valid
This bit is set when a new value is written to the PERBUF register. This bit is automatically
cleared on an UPDATE condition.
