FCR (UART0 FIFO CONTROL REGISTER, 0x2502)
Note: FCR register uses the same address as IIR register in Table 17 above. IIR register is read-only
and FCR register is write-only.

Trigger Level of Receiver FIFO. Interrupt occurs when FIFO
receives the the number of data bytes based on this field’s value
below. For example, when URXFTRIG field is set to ‘3’, interrupt
does not occur until FIFO receives 14 bytes.
Reserved
When this field is set to ‘1’, Transmitter FIFO is cleared and the
circuits related to it are reset.
When this field is set to ‘1’, Receiver FIFO is cleared and the
circuits related to it are reset.
Reserved
Divisor Latch Access Enable. When this field is set to ‘1’, Divisor
register (DLM, DLL) can be accessed. When this field is set to ‘0’,
general register can be accessed.
Set Break. When this field is set to ‘1’, serial output is forced to be
‘0’ (break state)
Stick Parity. When PEN and EPS are ‘1’ with this field set to ‘1’, a
parity of ‘0’ is transmitted. In reception mode, it checks whether
parity value is ‘0’ or not. When PEN is ‘1’ and EPS is ‘0’ with this
field is to ‘1’, parity of ‘1’, is transmitted. In reception mode, it
checks whether parity value is ‘1’ or not.
Even Parity Enable. When this field is set to ‘1’, parity value is
even. When set to ‘0’, parity value is odd.
Parity Enable. When this field is set to ‘1’, parity is calculated for
the byte to be transmitted and transferred with it. In reception
mode, checks parity. When this field is ‘0’, parity is not generated.
