Pin Name Pin No I/O Description
MCIF_BUSCLK 98 I MCIF Bus Clock. This pin is only used for the MCIF
synchronous mode. (MPC850 I/O Access) and the Memory
Access.
This signal should be tied high if not used.
In Serial MCIF Mode, this pin is used for the Serial Write Clock
(SMCIF_WCLK.)
MCIF_CS_IOZ 90 I MCIF Chip Select for all I/O MCIF modes.
In Serial MCIF Mode, this pin is used for the Serial Write
Request (SMCIF_WREQZ.)
MCIF_CS_MEMZ 91 I/O MCIF Chip Select for the Memory MCIF mode.
In Serial MCIF Mode, this pin is used for the Serial Write
Acknowledge (SMCIF_WACKZ.)
MCIF_DATA0 99 I/O MCIF DATA 0 pin. This data pin is the least significant bit of
the MCIF Data Bus.
In Serial MCIF Mode, this pin is used for the Serial Read Data
(SMCIF_RDATA.)
MCIF_DATA1 100 I/O MCIF DATA 1 pin.
MCIF_DATA10 111 I/O MCIF DATA 10 pin.
MCIF_DATA11 112 I/O MCIF DATA 11 pin.
MCIF_DATA12 113 I/O MCIF DATA 12 pin.
MCIF_DATA13 114 I/O MCIF DATA 13 pin.
MCIF_DATA14 118 I/O MCIF DATA 14 pin.
MCIF_DATA15 119 I/O MCIF DATA 15 pin. This data pin is the most significant bit of
the MCIF Data Bus.
MCIF_DATA2 103 I/O MCIF DATA 2 pin.
MCIF_DATA3 104 I/O MCIF DATA 3 pin.
MCIF_DATA4 105 I/O MCIF DATA 4 pin.
MCIF_DATA5 106 I/O MCIF DATA 5 pin.
MCIF_DATA6 107 I/O MCIF DATA 6 pin.
MCIF_DATA7 108 I/O MCIF DATA 7 pin.
MCIF_DATA8 109 I/O MCIF DATA 8 pin.
MCIF_DATA9 110 I/O MCIF DATA 9 pin.
MCIF_ENDIAN 132 I MCIF Endian Pin. This sets the Endianess for accesses
between the external CPU and the internal iceLynx-Micro
memory. This pin sets Endianess for all MCIF modes and the
Serial MCIF mode.
When set to a logical 0, data is read/written to the ex-CPU
exactly as it is stored in iceLynx-Micro memory. (Big Endian)
When set to a logical 1, data is swapped on half-word and
byte boundaries before it is read/written to the ex-CPU. (Little
Endian)
