PRESC register
| PRESCALER | PRESCALER[3:0]: Clock prescaler The USART input clock can be divided by a prescaler: -0000: input clock not divided -0001: input clock divided by 2 -0010: input clock divided by 4 -0011: input clock divided by 6 -0100: input clock divided by 8 -0101: input clock divided by 10 -0110: input clock divided by 12 -0111: input clock divided by 16 -1000: input clock divided by 32 -1001: input clock divided by 64 -1010: input clock divided by 128 -1011: input clock divided by 256 Remaing combinations: Reserved. Note: When PRESCALER is programmed with a value different of the allowed ones, programmed prescaler value will be ‘1011’ i.e. input clock divided by 256 |
