17.10 Baud Rate Generation
MMC2114 • MMC2113 • MMC2112 — Rev. 1.0
MOTOROLA
Serial Communications Interface Modules (SCI1 and SCI2)
A 13-bit modulus counter in the baud rate generator derives the baud
rate for both the receiver and the transmitter. The value from 0 to 8191
written to SCIBDH and SCIBDL determines the system clock divisor.
The baud rate clock is synchronized with the bus clock and drives the
receiver. The baud rate clock divided by 16 drives the transmitter. The
receiver acquisition rate is 16 samples per bit time.
Baud rate generation is subject to two sources of error:
SBR[12:0]
1. Integer division of the module clock may not give the exact target
2. Synchronization with the bus clock can cause phase shift.
