1-CH FULL-SPEED USB UART

CHARACTER_FORMAT Register Description (Read/Write)
This register controls the character format such as the word length (7, 8 or 9), parity (odd, even, forced ’0’, or
forced ’1’) and number of stop bits (1 or 2).
CHARACTER_FORMAT[3:0]: Data Bits.
All other values for CHARACTER_FORMAT[3:0] are reserved.
CHARACTER_FORMAT[6:4]: Parity Mode Select
These bits select the parity mode. If 9-bit data mode has been selected, then writing to these bits will not have
any effect. In other words, there will not be an additional parity bit.
CHARACTER_FORMAT[7]: Stop Bit select
This register selects the number of stop bits to add to the transmitted character and how many stop bits to
check for in the received character.
3.3.6
FLOW_CONTROL Register Description (Read/Write)
These registers select the flow control mode. These registers should only be written to when the UART is
disabled.
Writing to the FLOW_CONTROL register when the UART is enabled will result in undefined
behavior. Note that the FLOW_CONTROL register settings are used in conjunction with the GPIO_MODE
register.
