18.3.4.2 Port Control

Note: The SSCs in the TC1728 do not directly control the I/O functionality of pins.
Therefore, control bits CON.EN and CON.MS have no functionality.
The interconnections between the SSC modules and the I/O lines/pins are controlled by
software in the port logics. The SSC0/SSC1/SSC2/SSC3 I/O functionality must be
selected by the following port control operations (additionally to the PISEL
programming):
• Input/output function selection (IOCR registers)
• Pad driver characteristics selection for the outputs (PDR registers)
The SSC0/SSC1/SSC2/SSC3 port input/output control registers contain the bit fields
that select the digital output and input driver characteristics such as pull-up/down
devices, port direction (input/output), open-drain, and alternate output selections.
