I/O
I/O
These pin are dual mode pins. After power is supplied to the chip, the pin is
set to input mode for a while and receive INTFx[2:0] input. After that, the pins
are set to output mode and outputs RXEN#x as auto toggle.
RX Enable: This pins are for auto tri-state control of the RS422 or RS485
communication. When serial date is transmitted to TXD, the value set on
ATR[7] is transmitted. These pins eliminate additional glue logic outside.
Line Interface Type Select: These pins are used to select the type of Line
Transceiver interfaced in Serial port Mode. The inputted value from these pins
is shown in IIR0[5:4] of the Option register.
000b: RS232 interface is selected.
100b: RS422 1:1 interface is selected.
101b: RS422 Multi-Drop interface is selected.
110b: RS485 Non-Echo interface is selected.
111b: RS485 Echo interface is selected.

I/O
These pins works as the data I/O of Parallel Port in 1P and 2S1P mode and
the 8-bit data I/O of MIO Bus
TM
in 4S and 6S mode.
Parallel Port Data Bus: These pins are data bus of Parallel Port in 1P and
2S1P mode.
MIO Bus Data Bus: These pins are data bus of MIO Bus
TM
in 4S and 6S
mode.
BUSY_MIRQ2
76
I
These pins works as BUSY in 1P and 2S1P mode and MIRQ2 of MIO Bus
TM
in 4S and 6S mode.
Parallel Port Busy: This pin is asserted by peripheral when the peripheral
isn’t ready to receive data.
MIO Bus Interrupt Request 2: This pin is an interrupt request for 3
th
UART
channel among the external Quad-UART channel in 4S and 6S mode.
ACK#_MIRQ1
75
I
These pins works as ACK# in 1P and 2S1P mode and MIRQ1 of MIO Bus
TM
in
4S and 6S mode.
Parallel Port Acknowledge: This pin is asserted by printer to indicate that
data transfer is succeeded and it is ready for new data.
MIO Bus Interrupt Request 1: This pin is an interrupt request for 2
nd
UART
channel among the external Quad-UART channel in 4S and 6S mode.
PE_MIRQ0
74
I
These pins works as PE in 1P and 2S1P mode and MIRQ0 of MIO Bus
TM
in
4S and 6S mode.
Parallel Port Paper Empty: This pin is activated by printer when it runs out of
paper.
MIO Bus Interrupt Request 0: This pin is an interrupt request for 1
st
UART
channel among the external Quad-UART channel in 4S and 6S mode.
