0 = Timer 2 is a low priority.

1 = Timer 2 is a high-priority interrupt.

Serial port 0 interrupt. This bit controls the priority of the serial port 0 interrupt.

0 = Serial port 0 is a low priority.

1 = Serial port 0 is a high-priority interrupt.

Slave address mask enable register 0. This register is a mask enable when comparing serial port 0
addresses for automatic address recognition. When a bit is set in this register, the corresponding bit

location in the SADDR0 register is exactly compared with the incoming serial port 0 data to determine

if a receive interrupt should be generated. When a bit in this register is cleared, the corresponding bit

in the SADDR0 register becomes a “don’t care” and is not compared against the incoming data. All

incoming data generates a receive interrupt when this register is cleared.
