Bit 15 – RREQ Read Request
Writing a zero to this bit has no effect.
This bit will always read as zero.
Writing a one to this bit requests synchronization of the register pointed to by the Address bit group (READREQ. ADDR) and sets the Synchronization Busy bit in the Status register (STATUS.SYNCBUSY).
Bit 14 – RCONT Read Continuously
When continuous synchronization is enabled, the register pointed to by the Address bit group (READREQ.ADDR) will be synchronized automatically every time the register is updated.
READREQ.RCONT prevents READREQ.RREQ from clearing automatically. For the continuous read mode, RREQ bit is required to be set once the RCONT bit is set.
| Value | Description |
|---|---|
| 0 | Continuous synchronization is disabled. |
| 1 | Continuous synchronization is enabled. |
Bits 4:0 – ADDR[4:0] Address
These bits select the offset of the register that needs read synchronization. In the TC, only COUNT and CCx are available for read synchronization.
