Register block
Fields
cfg: CFG
0x00 - USART Configuration register. Basic USART configuration settings that typically are not changed during operation.
ctl: CTL
0x04 - USART Control register. USART control settings that are more likely to change during operation.
stat: STAT
0x08 - USART Status register. The complete status value can be read here. Writing ones clears some bits in the register. Some bits can be cleared by writing a 1 to them.
intenset: INTENSET
0x0c - Interrupt Enable read and Set register. Contains an individual interrupt enable bit for each potential USART interrupt. A complete value may be read from this register. Writing a 1 to any implemented bit position causes that bit to be set.
intenclr: INTENCLR
0x10 - Interrupt Enable Clear register. Allows clearing any combination of bits in the INTENSET register. Writing a 1 to any implemented bit position causes the corresponding bit to be cleared.
rxdat: RXDAT
0x14 - Receiver Data register. Contains the last character received.
rxdatstat: RXDATSTAT
0x18 - Receiver Data with Status register. Combines the last character received with the current USART receive status. Allows DMA or software to recover incoming data and status together.
txdat: TXDAT
0x1c - Transmit Data register. Data to be transmitted is written here.
brg: BRG
0x20 - Baud Rate Generator register. 16-bit integer baud rate divisor value.
intstat: INTSTAT
0x24 - Interrupt status register. Reflects interrupts that are currently enabled.
osr: OSR
0x28 - Oversample selection register for asynchronous communication.
addr: ADDR
0x2c - Address register for automatic address matching.
