In the SCLK output mode, if SC0MOD2 <WBUF> = “0” and receive double buffering is
disabled, a synchronous clock pulse is output from the SCLK0 pin and the next data is
shifted into receive buffer 1 each time the CPU reads received data. When all the 8 bits
are received, the INTRX0 interrupt is generated.
The first SCLK output can be started by setting the receive enable bit SC0MOD0
<RXE> to “1.” If the receive double buffering is enabled with SC0MOD2 <WBUF> set
to “1,” the first frame received is moved to receive buffer 2 and receive buffer 1 can
receive the next frame successively. As data is moved from receive buffer 1 to receive
buffer 2, the receive buffer full flag SC0MOD2 <RBFULL> is set to “1” and the INTRX0
interrupt is generated.
While data is in receive buffer 2, if CPU/DMAC cannot read data from receive buffer 2
before completing reception of the next 8 bits, the INTRX0 interrupt is not generated
and the SCLK0 clock stops. In this state, reading data from receive buffer 2 allows data
in receive buffer 1 to move to receive buffer 2 and thus the INTRX0 interrupt is
generated and data reception resumes.
