Clock pulse counter
In a noisy environment, the number of pulses received on Serial Clock (C) may be greater
than the number delivered by the master (the microcontroller). This can lead to a
misalignment of the instruction of one or more bits (as shown in
the writing of erroneous data at an erroneous address.
To combat this problem, the M93Cx6 has an on-chip counter that counts the clock pulses
from the start bit until the falling edge of the Chip Select Input (S). If the number of clock
pulses received is not the number expected, the WRITE, ERASE, ERAL or WRAL
instruction is aborted, and the contents of the memory are not modified.
The number of clock cycles expected for each instruction, and for each member of the
M93Cx6 family, are summarized in
Memory (WRITE) instruction on the M93C56 (or M93C66) expects 20 clock cycles (for the
x8 organization) from the start bit to the falling edge of Chip Select Input (S). That is:
