14.3.12 UART Interrupt Vector Register (UIVRn)
The UIVRn, Figure 14-14, contain the 8-bit internal interrupt vector number (IVR).
Table 14-10 describes UIVRn fields.
14.3.13 UART Input Port Register (UIPn)
The UART input port registers (UIPn), Figure 14-15, show the current state of the CTS
input.
Table 14-11 describes UIPn fields.
14.3.14 UART Output Port Command Registers
In UART mode, the RTS output can be asserted by writing a 1 to UOP1n[RTS] and negated
by writing a 1 to UOP0n[RTS]. See Figure 14-16.

Current state. The CTS value is latched and reflects the state of the input pin when UIPn is read.
Note: This bit has the same function and value as UIPCRn[RTS].
0 The current state of the CTS input is logic 0.
1 The current state of the CTS input is logic 1.
7
Interrupt vector. Indicates the vector number where the address of the exception handler for the
specified interrupt is located. UIVRn is reset to 0x0F, indicating an uninitialized interrupt condition.
