Note: All bits in this register are latched and can create interrupts. See
Bit 7: Loss of Receive Clock Condition Clear (LORCC). Falling edge detect of LORC. Set when an LORC
condition was detected and then removed.
Bit 6: Spare Code Detected Condition Clear (LSPC). Falling edge detect of LSP. Set when a spare-code match
condition was detected and then removed.
Bit 5: Loop-Down Code Detected Condition Clear (LDNC). Falling edge detect of LDN. Set when a loop-down
condition was detected and then removed
Bit 4: Loop-Up Code Detected Condition Clear (LUPC). Falling edge detect of LUP. Set when a loop-up
condition was detected and then removed.
Bit 3: Loss of Receive Clock Condition Detect (LORCD). Rising edge detect of LORC. Set when the RCLK pin
has not transitioned for one channel time.
Bit 2: Spare Code Detected Condition Detect (LSPD). Rising edge detect of LSP. Set when the spare code as
defined in the
