5.3.10 Configuration B register
ECR[7:5] must be set to ‘111’ to access this register. Read
only, all bits will be set to 0, except for bit[6] which will
reflect the state of the interrupt.
5.3.11 Extended control register ‘ECR’
The Extended control register is located at offset 002h in
upper block. It is used to configure the operation of the
parallel port.
ECR[4:0]: Reserved - write
These bits are reserved and must always be set to
“00001”.
ECR[0]: Empty - read
When DCR[5} = ‘0’
logic 0
FIFO contains at least one byte
logic 1
FIFO completely empty
When DCR[5} = ‘1’
logic 0
FIFO contains at least one byte
logic 1
FIFO contains less than one byte
ECR[1]: Full - read
When DCR[5} = ‘0’
