Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
23
DMAEN
DMA Transfer Enabled
This bit is used together with the TSI interrupt enable bits(TSIIE, ESOR) to generate a DMA transfer
request instead of an interrupt.
0 Interrupt is selected when the interrupt enable bit is set and the corresponding TSI events assert.
1 DMA transfer request is selected when the interrupt enable bit is set and the corresponding TSI
events assert.
22
SWTS
Software Trigger Start
This write-only bit is a software start trigger. When STM bit is clear, write "1" to this bit will start a scan.
The electrode channel to be scanned is determinated by TSI_DATA[TSICH] bits.
0 No effect.
1 Start a scan to determine which channel is specified by TSI_DATA[TSICH].

Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
TSICNT TSI Conversion Counter Value
These read-only bits record the accumulated scan counter value ticked by the reference oscillator.
