6.4.8 Register Description
6.4.8.1
SSC Control Register SSCCON
The bit addressable register SSCCON provides the basic control of the SSC functions like general
enable/disable, mode selections and transmitter control.
Special Function Registers SSCCON (Address E8H)
Reset Value : 07H
Bit
Function
SCEN
SSC System Enable
SCEN =0 : SSC subsystem is disabled, related pins are available as general I/O.
SCEN=1 : SSC subsystem is enabled.
TEN
Slave Mode - Transmitter enable
TEN =0
: Transmitter output STO will remain in tristate state,
regardless of the state of SLS.
TEN=1 and SLS =0 : Transmitter will drive the STO output.
In master mode the transmitter will be enabled all the time, regardless of the setting
of TEN.
MSTR
Master Mode Select
MSTR=0 : Slave mode is selected
MSTR=1 : Master mode is selected
This bit has to be set to the correct value depending on the hardware setup of the
system before the SSC will be enabled. It must not be modified afterwards. There
is no on-chip support for dynamic switching between master and slave mode
operation.
CPOL
Clock Polarity
This bit controls the polarity of the shift clock and in conjunction with the CPHA bit
which clock edges are used for sample and shift.
CPOL=0 : SCLK idle state is low.
CPOL=1 : SCLK idle state is high.
