The 16C95X chip has several registers that are used to configure and control its operation. These registers include:
In Zephyr RTOS, the 16C95x is supported via the uart_ns16550.c driver with a HAS_UART_NS16550_16C95X Kconfig flag. It enables extended register mapping. 16c95x serial port driver
Many 16C95x chips support automatic direction control for RS-485 communication, which the driver must toggle. The 16C95X chip has several registers that are
The CPU working harder than necessary to manage data. 16c95x serial port driver
These enhancements allow a driver to service interrupts much less frequently while sustaining high data rates, reducing context switching and CPU load.
