HIP: High Priority Interrupt Status. When set, it indicates that software is servicing a high priority
interrupt. This bit will be cleared when the program executes the corresponding RETI
instruction.
LIP: Low Priority Interrupt Status. When set, it indicates that software is servicing a low priority
interrupt. This bit will be cleared when the program executes the corresponding RETI
instruction.
XTUP: Crystal Oscillator Warm-up Status. When set, this bit indicates CPU has detected clock to
be ready. Each time the crystal oscillator is restarted by exit from power down mode,
hardware will clear this bit. This bit is set to 1 after a power-on reset.
SPTA1: Serial Port 1 Transmit Activity. This bit is set during serial port 1 is currently transmitting
data. It is cleared when TI_1 bit is set by hardware. Changing the Clock Divide Control bits
CD0, CD1 will be ignored when this bit is set to 1 and SWB = 1.
SPRA1: Serial Port 1 Receive Activity. This bit is set during serial port 1 is currently receiving a
data. It is cleared when RI_1 bit is set by hardware. Changing the Clock Divide Control bits
CD0, CD1 will be ignored when this bit is set to 1 and SWB = 1.
SPTA0: Serial Port 0 Transmit Activity. This bit is set during serial port 0 is currently transmitting
data. It is cleared when TI bit is set by hardware. Changing the Clock Divide Control bits
CD0, CD1 will be ignored when this bit is set to 1 and SWB = 1.
SPRA0: Serial Port 0 Receive Activity. This bit is set during serial port 0 is currently receiving a
data. It is cleared when RI bit is set by hardware. Changing the Clock Divide Control bits
CD0, CD1 will be ignored when this bit is set to 1 and SWB = 1.

Mnemonic: NVMSEL
Address: C6h
DCID[5:0]: 6-bit address to access individual location of on-chip 64 bytes non-volatile data memory.
For instance, asserting DCID[5:0] = 00000b addresses to the NVM 1
st
byte, DCID[5:0] =
11111b addresses to the NVM 64
th
byte.
