32-Bit System-on-Chip
the serial frame pin (SSPFRM) is active LOW. Both the
SSP and external slave device drive their output data
on the falling edge of the clock, and latch data from the
other device on the rising edge of the clock. Unlike the
full-duplex transmission of the other two frame formats,
the National Semiconductor MICROWIRE format uti-
lizes a master-slave messaging technique that oper-
ates in half-duplex. When a frame begins in this mode,

8-BIT CONTROL

an 8-bit control message is transmitted to the off-chip
slave. During this transmission no incoming data is
received by the SSP. After the message has been sent,
the external slave device decodes the message. After
waiting one serial clock period after the last bit of the 8-
bit control message was received it responds by return-
ing the requested data. The returned data can be 4 to
16 bits in length, making the total frame length between
13 to 25 bits. See Figure 24 and Figure 25.
