AAR is only available when using the serial port in either
mode 2 or 3. Setting the SM2 bit in SCON enables AAR.
Each slave must have its SM2 bit set when waiting for an
address (9th bit = 1). The Receive Interrupt (RI) flag will only
be set when the received byte matches either the Given or
Broadcast Address. The slave then clears its SM2 bit to
enable reception of data bytes (9th bit = 0) from the master.
The master can selectively communicate with groups of
slaves by sending the Given Address. Addressing all
slaves is also possible by sending the Broadcast address.
The SADDR and SADEN special function registers define
these addresses for each slave.
SADDR specifies a slaves individual address and SADEN
is a mask byte that defines don’t-care bits to form the Given
address when combined with SADDR. The following is an
example:
In this example Slave 1 can be distinguished from Slave 2
by using bits 0 and 1. Slave 1 will not respond to an
address that has bit 1 set to 1 while Slave 2 will. Similarly,
Slave 2 will not respond to an address that has bit 0 set to 0
while Slave 1 will. Both slaves will respond to an address of
1111 0x01b so this is the Broadcast Address. The Broad-
cast Addresses is formed by the logical OR of SADDR and
SADEN with 0s treated as don’t-care bits.
6.2 Serial Peripheral Interface (SPI)
The device SPI allows for high-speed full-duplex synchro-
nous data transfer between the device and other compati-
ble SPI devices.
Figure 6-1 shows the correspondence between master
and slave SPI devices. The SCK pin is the clock output and
input for the master and slave modes, respectively. The SPI
clock generator will start following a write to the master
devices SPI data register. The written data is then shifted
out of the MOSI pin on the master device into the MOSI pin
of the slave device. Following a complete transmission of
one byte of data, the SPI clock generator is stopped and
the SPIF flag is set. An SPI interrupt request will be gener-
ated if the SPI interrupt enable bit (SPIE) and the serial port
interrupt enable bit (ES) are both set.
An external master drives the Slave Select input pin, SS#/
P1[4], low to select the SPI module as a slave. If SS#/P1[4]
has not been driven low, then the slave SPI unit is not
active and the MOSI/P1[5] port can also be used as an
input port pin.
CPHA and CPOL control the phase and polarity of the SPI
clock. Figures 6-2 and 6-3 show the four possible combina-
tions of these two bits.
