IPCS (SPI Slave)

For parts that are not locked, the Eterna Flash emulator uses the IPCS bus in

conjunction with the RESETn and FLASH_P_ENn signals. To enter the flash emulator,

assert both RESETn and FLASH_P_ENn (both low), and then after 10ms, the host

communicate with the emulator via the bus, at a maximum rate of 3.33 MHz.

Operation is controlled by a protocol mastered externally. Commands starts with the

falling edge of IPCS_SSn followed by an appropriate 8-bit instruction, listed below,

followed by appropriate address and/or data. While IPCS_SSn is low, data from

IPCS_MOSI is clocked from the master on the rising edge of IPCS_SCK, MSB first.

As appropriate, status and read data from the device is clocked out on IPCS_MISO on

the falling edge of IPCS_SCK, for sampling by the master on the rising edge.
