| Name: | CTRLA |
| Offset: | 0x00 |
| Reset: | 0x00 |
| Property: | - |
| Bit | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |
| | | RUNSTDBY | | SYNCUPD | | CLKSEL[1:0] | ENABLE | |
| Access | | R/W | | R/W | | R/W | R/W | R/W | |
| Reset | | 0 | | 0 | | 0 | 0 | 0 | |
Bit 6 – RUNSTDBY Run in
Standby
Writing a
‘1’ to this bit will enable the peripheral to run in Standby
Sleep mode. Not applicable when CLKSEL is set to 0x2
(CLK_TCA).
Bit 4 – SYNCUPD Synchronize Update
When this bit is
written to ‘1’, the TCB will restart whenever TCA0 is restarted or
overflows. This can be used to synchronize capture with the PWM
period.
Bits 2:1 – CLKSEL[1:0] Clock Select
Writing these bits
selects the clock source for this peripheral.
| Value | Name | Description |
|---|
| 0x0 | CLKDIV1 | CLK_PER |
| 0x1 | CLKDIV2 | CLK_PER / 2 |
| 0x2 | CLKTCA | Use CLK_TCA from TCA0 |
| 0x3 | | Reserved |
Bit 0 – ENABLE Enable
Writing this bit to
‘1’ enables the Timer/Counter type B
peripheral.
