XC164-16 Derivatives
Peripheral Units (Vol. 2 of 2)
High-Speed Synchronous Serial Interface (SSC)
MSCLK (Master Serial Shift Clock) or input via line SSCLK (Slave Serial Shift Clock).
Both lines are connected to pin SCLK. These pins are alternate functions of port pins.
A block diagram of the SSC Module is shown in Figure 20-2.
From the programmer’s point of view, the term ‘SSC unit’ refers to a set of registers (see
Figure 20-1) which are associated with this peripheral, including the port pins which may
be used for alternate input/output functions, and including their direction control bits.
