Description
MCIF_INTZ
89
O
MCIF Interrupt. This signal is push-pull. (always asserted) It
does not require a pull-up resistor.
MCIF_MODE0
133
I
MCIF Mode 0. Used to select MCIF mode.
MCIF_MODE1
134
I
MCIF Mode 1. Used to select MCIF mode.
MCIF_MODE2
135
I
MCIF Mode 2. Used to select MCIF mode.
MCIF_OEZ
96
I
MCIF Output Enable. Default active low. This input pin
indicates if the system CPU wants to perform a MCIF read
access. This signal is used for the following modes:
•
SH-3 I/O Access
•
M16C/62 I/O Access
• Memory
Access
This signal should be tied high if not used.
MCIF_RW
92
I
MCIF Read/Write pin. Default value for read is a logical 1.
Default value for write is a logical 0.
In Serial MCIF Mode, this pin is used for the Serial Write Data
(SMCIF_WDATA.)
MCIF_STRBZ
93
I
MCIF Strobe pin. Default active low. This pin is used (along
with MCIF_CS_IOZ) to validate the MCIF access. This signal
is used for the following modes:
•
68000 + Wait I/O Access
•
MPC850 I/O Access
•
When not used, this pin should be tied high.
In Serial MCIF Mode, this pin is used for the Serial Read
Clock (SMCIF_RCLK.)
MCIF_WAIT
94
O
MCIF Wait pin. Default active high. iceLynx-Micro asserts
this signal if it is not ready to service an MCIF request. When
not asserted, this signal is in high-Z state. This signal is used
for the following modes:
•
68000 + Wait I/O Access
•
SH-3 I/O Access
•
M16C/62 I/O Access
In Serial MCIF Mode, this pin is used for the Serial Read
Request (SMCIF_RREQZ.)
MCIF_WEZ
97
I
MCIF Write Enable. Default active low. This input pin
indicates if the system CPU wants to perform a MCIF write
access. This signal is used for the following modes:
•
SH-3 I/O Access
•
M16C/62 I/O Access
• Memory
Access
This signal should be tied high if not used.
Universal Asynchronous Receiver Transmitter Pins
UART_RxD
86
I
UART receive port. Data from the system is input to the
UART buffer using this pin.
UART_TxD
85
O
UART transmit port. Data from the UART buffer is output to
the system using this pin.
