10.4.6 Automatic Increment of Address Pointer
The N35P112 slave automatically increments the address pointer after each byte transferred. The increase of the address pointer is independent
from the address being valid or not.
10.4.7 Invalid Addresses
If the user sets the address pointer to an invalid address, the address byte is not acknowledged. Nevertheless a read or write cycle is possible.
The address pointer is increased after each byte.
Reading:
When reading from a wrong address, the N35P112 slave returns all zero. The address pointer is increased after each byte.
Sequential read over the whole address range is possible including address overflow.
Writing:
A write to a wrong address is not acknowledged by the N35P112 slave, although the address pointer is increased. When the address
pointer points to a valid address again, a successful write accessed is acknowledged. Page write over the whole address range is possible
including address overflow.
10.5 SDA, SCL Input Filters
Input filters for SDA and SCL inputs are included to suppress noise spikes of less than 50ns. Furthermore, the SDA line is delayed by 120ns to
provide an internal hold time for Start/Stop detection to bridge the undefined region of the falling edge of SCL. The delay needs to be smaller
than t
260ns.
HD.STA
For Standard-mode and Fast-mode an internal hold time of 300ns is required, which is not covered by the N35P112 slave.
