13 Serial channel (UART/SIO)

1) Division by an integer (divide by N):
2) For divide by N + (16-K)/16 (only for UART mode):
Example baud rate setting:
Also, an external clock input may be used as the serial clock. The resulting baud rate
calculation is shown below:
= 39.321 × 10

Selecting fc = 39.321 MHz for fperiph, setting φT0 to fperiph/16, using the baud rate
generator input clock φT1, setting the divide ratio N (SC0BRCR<BR0S3:0>) = 4, and
setting SC0BRCR<BR0ADDE> = “0,” the resulting baud rate in the UART mode is
calculated as follows:
Selecting fc = 9.6 MHz for fperiph, setting φT0 to fperiph/8, using the baud rate
generator input clock φT1, setting the divide ratio N (SC0BRCR<BR0S3:0>) = 7,
setting K (SC0BRADD<BR0K3:0>) = 3, and selecting SC0BRCR<BR0ADDE> = 1,
the resulting baud rate is calculated as follows:
= 9.6 × 10
The divide by (N + (16-K)/16) function is inhibited and thus SC0BRADD
<BR0K3:0> is ignored.
