To use the KS8995M SPI:
M9999-062309
1. At the board level, connect KS8995M pins as follows:
KS8995M
Pin Number
112
110
111
109
2. Set the input signals PS[1:0] (pins 113 and 114 respectively) to “10” to set the serial configuration to SPI slave mode.
3. Power up the board and assert a reset signal. After reset, the start switch bit in register 1 will be set to ‘0’. Configure
4. Write configuration to registers using a typical SPI write data cycle as shown in Figure 8 or SPI multiple write as shown
5. Registers can be read and configuration can be verified with a typical SPI read data cycle as shown in Figure 9 or
6. After configuration is written and verified, write a ‘1’ to register 1 bit 0 to begin KS8995M operation.
the desired settings in the KS8995M before setting the start register to ‘1’.
in Figure 10. Note that data input on SPID is registered on the rising edge of SPIC.
a multiple read as shown in Figure 11. Note that read data is registered out of SPIQ on the falling edge of SPIC.
