Memory Map

Base Address	Bank Name	Description
0x00000000	UART_CH1	Provides control and status for UART_CH1
0x01000000	UART_CH2	Provides control and status for UART_CH2
0x02000000	RESERVED	RESERVED
0x03000000	RESERVED	RESERVED
0x04000000	RESERVED	RESERVED

Note

Memory Maps are typically divided into regions, or banks to organize and partition a design’s functionality

UART_CH1

Offset	Register Name	Description	Default Value
0x0	UART_CH1_EN_POKE	Enables UART channel	0x00000000
0x4	UART_CH1_RATE_POKE	Selects UART rate	0x00000000
0x8	UART_CH1_TX_FIFO_POKE	Buffers UART TX data	0x00000000
0xC	UART_CH1_TX_SEND_POKE	Enables UART transmission of FIFO data	0x00000000
0x10	UART_CH1_RX_FIFO_PEEK	Buffers UART RX data	0x00000000

Note

The registers in this template are either read-only/write-only and adopt the following naming convention, to be as descriptive as possible and intuitive to work with from an end-user perspective: <BANK NAME>_<FUNCTION>_<POKE/PEEK>
