the trailing edge of the CS signal.
MB85RS256 outputs the 8-bit data synchronized with the clock. Thereafter, the address can be
incremented automatically to read 8 more bits of data repeatedly by inputting 8 clock pulses
before raising the CS signal.
The commands listed above are input to the FRAM synchronized with the clock (SCK) after
Reading is done by inputting the READ command followed by a 16-bit address. In response,
CS
SCK
SI
SO
Command 0x03
Address can be incremented automatically to
read another byte of data by inputting 8 cycles
of SCK before raising CS.
