FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Figure 19 illustrates content of the HC08/12 SPI Data
Register and the SBC SPI Data Register before the
transmission. The new address and R/W bits are already in
the SPI Data Register while the new data and parity bits are
still in an appropriate microcontroller register or memory. This
second byte has to be loaded into the HC08/12 SPI Data
Register after the first byte was transmitted to the SBC.
Figure 19. Microcontroller SPI Reading Data - Sequence A
After transmission of the first byte, the HC08/12 SPI read buffer contains the old address and R/W bits received from the SBC.
An appropriate operation in the microcontroller loads the new data and parity into the HC08/12 SPI Data Register (second byte).
In the SBC the internal logic loads P3-P0 and D3-D0 to the location of Bit 15 to Bit 8 in the SBC SPI Data Register, shifting this
data within the remaining eight clock cycles. Please see Figure 20.
Figure 20. Microcontroller SPI Reading Data - Sequence B
After sixteen clock cycles, the microcontrollers read buffer contains the new parity, and data and is now ready for the next
transmission. Please see Figure 21.
