Industrial UART Baud Rate Generation FAQ
| Q | What is the highest baud rate produced by an internal clock? |
| A |
The highest baud rate is an X1 clock input divided by 16.
For example:
At 3.6864Mhz, the highest baud rate is 3.6864M/16 = 230.4K baud. At 8Mhz, the highest baud rate is 8M/16 = 500K baud. |
| Q | What is the maximum baud rate in timer mode with a crystal of 3.6864Mhz? |
| A | The maximum baud rate is a C/T clock input divided by 64. For example, at 3.6864Mhz, the maximum baud rate is 3.6864M/(2*16*2) = 57.6K baud. |
| Q | If the crystal of 3.6864Mhz is doubled, will the baud rates in each column in the baud rate selection table be doubled? |
| A | Yes. For example, if a crystal of 7.3728Mhz (2*3.6864Mhz) is used, the baud rates will be doubled as follows: The 57.6K and 115.2K in one column will become 115.2K and 230.4K. |
