15.4.10
The UISR registers provides status for all potential interrupt sources. The UART Interrupt Mask Register
(UIMR) masks the contents of this register. If a flag in the UISR is set and the corresponding bit in UIMR
is also set, the internal interrupt output is asserted. If the corresponding bit in the UIMR is cleared, the state
of the bit in the UISR has no effect on the interrupt output.

1 UISR bit 7 is set and generates an interrupt when the COS bit in the UART Input Port Change Register (UIPCR)
0 Setting the corresponding bit in the UIPCR has no effect on UISR bit 7.

Input Enable Control
is set by an external transition on the CTS input (if bit 7 of the interrupt mask register (UIMR) is set to enable
interrupts).
Interrupt Status Registers (UISRn)
COS
The UIMR does not mask reading of the UISR. True status is provided
regardless of the contents of UIMR. A UART module reset clears the
contents of UISR.
