P89V660/662/664
80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI
In a more complex system the following could be used to select slaves 1 and 2 while
excluding slave 0:
Example 1, slave 0:
(6)
Example 2, slave 1:
(7)
Example 2, slave 2:
(8)
In the above example the differentiation among the 3 slaves is in the lower 3 address bits.
Slave 0 requires that bit 0 = 0 and it can be uniquely addressed by 1110 0110. Slave 1
requires that bit 1 = 0 and it can be uniquely addressed by 1110 0101. Slave 2 requires
that bit 2 = 0 and its unique address is 1110 0011. To select Slaves 0 and 1 and exclude
Slave 2 use address 1110 0100, since it is necessary to make bit 2 = 1 to exclude slave 2.
The Broadcast Address for each slave is created by taking the logical OR of SADDR and
SADEN. Zeros in this result are treated as don’t-cares. In most cases, interpreting the
don’t-cares as ones, the broadcast address will be FF hexadecimal. Upon reset SADDR
and SADEN are loaded with 0s. This produces a given address of all ‘don’t cares’ as well
as a Broadcast address of all ‘don’t cares'. This effectively disables the Automatic
Addressing mode and allows the microcontroller to use standard UART drivers which do
not make use of this feature.
6.8 Serial Peripheral Interface (SPI)
6.8.1 SPI features
Master or slave operation
10 MHz bit frequency (max)
LSB first or MSB first data transfer
Four programmable bit rates
End of transmission (SPIF)
Write collision flag protection (WCOL)
Wake-up from Idle mode (slave mode only)
6.8.2 SPI description
The serial peripheral interface allows high-speed synchronous data transfer between the
P89V660/662/664 and peripheral devices or between several P89V660/662/664 devices.
Figure 23 shows the correspondence between master and slave SPI devices. The
SADDR = 1100 0000
SADEN = 1111 1001
Given = 1100 0XX0
----------------------------------------------------
SADDR = 1110 0000
SADEN = 1111 1010
Given = 1110 0X0X
----------------------------------------------------
SADDR = 1100 0000
SADEN = 1111 1100
Given = 1100 00XX
----------------------------------------------------
