这段代码有几个拼写错误和语法错误,应该进行以下更正:
```
library ieee;
use ieee.std_logic_1164.all;
entity BusTxRx is
port(
A, B : inout std_logic_vector(7 downto 0);
DIR, EN : in std_logic
);
end BusTxRx;
architecture a of BusTxRx is
begin
A <= B when (EN = '0') and (DIR = '0') else (others => 'Z');
B <= A when (EN = '0') and (DIR = '1') else (others => 'Z');
end a;
```
更正后,代码应该是可以正确编译和工作的。
