• Number of Data Bits - Defines the number of data bits used by the UART. Should
almost always be set to 8.
• Use Parity - Enable this parameter to use parity checking of the UART characters.
• Even or Odd Parity - Select odd or even parity. Only available when parity is used.
• Implement Receive Interrupt - Generate an interrupt when the UART has received a
character. When the interrupt is not enabled the UART must be polled to check if data
has been received.
• Implement Transmit Interrupt - Generate an interrupt when the UART has sent a
character. When the interrupt is not enabled the UART must be polled to wait until data
has been transmitted.
• Implement Error Interrupt - Generate an interrupt if an error occurs when the UART
receives a character. This error can be a framing error, an overrun error or a parity error
(if parity is used), When the interrupt is not enabled the UART must be polled to check
if an error has occurred after a character has been received.
The FIT Timer parameter tab showing the parameters for one of the four timers is shown in
Figure 4-3.
