Notes: 1. Outputs a clock of the same frequency as the bit rate.
2. Inputs a clock with a frequency 16 times the bit rate.
Transmit End Interrupt Enable
0 Transmit end interrupt (TEI) request disabled
1 Transmit end interrupt (TEI) request enabled
Multiprocessor Interrupt Enable
0 Multiprocessor interrupts disabled
[Clearing conditions]
• When the MPIE bit is cleared to 0
• When MPB= 1 data is received
