Bit Transfer
One data bit is transferred during each SCL clock cycle.
The data on SDA must remain stable during the high
period of the SCL clock pulse. Changes in SDA while
SCL is high and stable are considered control signals
(see the
START and STOP Conditions section). Both
SDA and SCL remain high when the bus is not active.
START and STOP Conditions
The master initiates a transmission with a START condi-
tion, a high-to-low transition on SDA while SCL is high.
The master terminates a transmission with a STOP con-
dition, a low-to-high transition on SDA while SCL is high
(see Figure 7).
Acknowledge Bits
Data transfers are acknowledged with an acknowledge
bit (ACK) or a not-acknowledge bit (NACK). Both the
master and the MAX11041 generates ACK bits. To gen-
erate an ACK, pull SDA low before the rising edge of
the ninth clock pulse and keep it low during the high
period of the ninth clock pulse (see Figure 8). To gener-
ate a NACK, leave SDA high before the rising edge of
the ninth clock pulse and keep it high for the duration of
the ninth clock pulse. Monitoring NACK bits allows for
detection of unsuccessful data transfers. The master
can also use NACK bits to interrupt the current data
transfer to start another data transfer. If the master uses
NACK during a read from the FIFO, the FIFO word
pointer is not incremented and the next FIFO read pro-
duces the same FIFO word. Thus, the master must pro-
vide the ACK bit to advance the FIFO word pointer.
Applications Information
Required Resistor Set
Table 4 shows the required resistor set for 30 key imple-
mentations. Resistors must have a 1% tolerance.
Jack Insertion/Removal Detection
During jack insertion there may be several
false key entries written to the FIFO. When a jack inser-
tion/removal is detected, it is necessary to read the
FIFO repeatedly until the final change in jack state is
located (see Figure 9).
Extended Keypresses
In certain applications, a key triggers different events
depending on the duration of the keypress, simultane-
ous keypresses, or a specific order of keypresses.
Long Keypress Detection
In some applications, the duration of the keypress
determines the event triggered. For example, TALK
dials the entered phone number normally and initiates
voice dialing if it is held down. A second common use
of holding a key down is to generate a continuous
stream of events, such as the volume control or
fast forward.
