10. Clock wake-up scheme
This section explains the ISP1109 clock stop timing, events triggering the clock to wake
up, and the timing of the clock wake-up.

Transfer format description for a multiple-byte read
Description
master starts with a START condition
master transmits device address and write command bit R/W = 0
slave generates an acknowledgment
master transmits (start) address of register K to be read from
slave generates an acknowledgment
master restarts with a START condition
master transmits device address and read command bit R/W = 1
slave generates an acknowledgment
slave transmits and master reads data from register K. After a byte is read,
the address is automatically incremented by 1.
slave generates an acknowledgment
Read data K + 1
slave transmits and master reads data from register K + 1
ACK
slave generates an acknowledgment
:
:
Read data K + N
1 slave transmits and master reads data register K + N
1. This is the last
register to read. After incrementing, the address rolls over to 0. Here, N
represents the number of addresses available in the slave.
No ACK
master terminates the read operation by generating a No Acknowledge
P
master generates a STOP condition
ACK
