SIGNAL NAMES
Signal
Direction
Description
CLK
Input
The primary clock used for all circuits in this interface.
RESET
Input
Active-high asynchronous reset.
START
Input
Strobe to start TWSI bus cycle.
ENABLE
Input
WHEN ASSERTED THE CORE WILL BE ENABLED. THIS MUST BE DRIVEN FROM A REGISTER.
STDFAST_N
Input
Select TWSI transfer speed mode. Set to ‘1’ for standard (100 kHz) or set to ‘0’ for fast (400 kHz).
DATA_IN[7:0]
Input
The data input vector.
ADDR_IN[6:0]
Input
The address input vector.
TWSI_CMD[2:0]
Input
The command input vector. Tells the core what TWSI command to perform (read/write, stop, repeated
start).
CFG[127:0]
Input
MC-TWSI conguration vector. Congures the options for the MC-TWSI core (SCL timer values, TWSI
mode, etc.).
DATA_VLD
Output
Asserted for one clock cycle to indicate a data byte has been received on the TWSI bus and is available
on DATA_OUT.
REQ_DATA
Output
Asserted for one clock cycle indicate a data byte is requested when sourcing data. Can be used to incre-
ment a data pointer.
FIRST_BYTE
Output
Indicates the byte just received is the rst data byte (of what may be a burst). Can be used as an enable
to latch the data byte (on DATA_OUT) as an offset in to a register or memory array.
STATUS[5:0]
Output
The STATUS bits are always available and are cleared when START is strobed.
DATA_OUT[7:0]
Output
The DATA_OUT port contains the data byte just received on the TWSI bus and is qualied with DATA_VLD
at the completion of a TWSI data phase.
SDA_IN
Input
This is the serial data line open collector input.
SDA_OUT
Output
This is the serial data line open collector output.
SCL_IN
Input
This is the serial clock line open collector input.
SCL_OUT
Output
This is the serial clock line open collector output.
SDA
External
TWSI serial data line.
SCL
External
TWSI serial clock line.
