R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-9 Unimplemented: Read as ‘0’
bit 8 HLVDIF: High/Low-Voltage Detect Interrupt Flag Status bit
1 = Interrupt request has occurred
0 = Interrupt request has not occurred
bit 7-3 Unimplemented: Read as ‘0’
bit 2 U2ERIF: UART2 Error Interrupt Flag Status bit
(1)
1 = Interrupt request has occurred
0 = Interrupt request has not occurred
