__IO uint32_t ACR |
Auto-baud Control Register. Contains controls for the auto-baud feature.
Definition at line 72 of file uart_112x.h.
__IO uint32_t DLL |
Divisor Latch LSB. Least significant byte of the baud rate divisor value. The full divisor is used to generate a baud rate from the fractional rate divider (DLAB = 1).
Definition at line 52 of file uart_112x.h.
__IO uint32_t DLM |
Divisor Latch MSB. Most significant byte of the baud rate divisor value. The full divisor is used to generate a baud rate from the fractional rate divider (DLAB = 1).
Definition at line 59 of file uart_112x.h.
__O uint32_t FCR |
FIFO Control Register. Controls UART FIFO usage and modes.
Definition at line 63 of file uart_112x.h.
__IO uint32_t FDR |
Fractional Divider Register. Generates a clock input for the baud rate divider.
Definition at line 74 of file uart_112x.h.
__IO uint32_t IER |
Interrupt Enable Register. Contains individual interrupt enable bits for the 7 potential UART interrupts (DLAB = 0).
Definition at line 58 of file uart_112x.h.
__I uint32_t IIR |
Interrupt ID Register. Identifies which interrupt(s) are pending.
Definition at line 64 of file uart_112x.h.
__IO uint32_t LCR |
Line Control Register. Contains controls for frame formatting and break generation.
Definition at line 67 of file uart_112x.h.
__I uint32_t LSR |
Line Status Register. Contains flags for transmit and receive status, including line errors.
Definition at line 69 of file uart_112x.h.
__IO uint32_t MCR |
Modem Control Register. Only present on UART ports with full modem support.
Definition at line 68 of file uart_112x.h.
__I uint32_t MSR |
Modem Status Register. Only present on UART ports with full modem support.
