TC1767
Introduction
• Trigger sources that do not depend on a clock, such as the PORST. This trigger force
the device into an asynchronous reset assertion independently of any clock. The
activation of an asynchronous reset is asynchronous to the system clock, whereas
its de-assertion is synchronized.
• Trigger sources that need a clock in order to be asserted, such as the input signals
ESR0, and ESR1, the WDT trigger, the parity trigger, or the SW trigger.
2.3.4.4 External Interface
The SCU provides interface pads for system purpose. Various functions are covered by
these pins. Due to the different tasks some of the pads can not be shared with other
functions but most of them can be shared with other functions. The following functions
are covered by the SCU controlled pads:
• Reset request triggers
• Reset indication
• Trap request triggers
• Interrupt request triggers
• Non SCU module triggers
The first three points are covered by the ESR pads and the last two points by the ERU
pads.
2.3.4.5 Die Temperature Measurement
The Die Temperature Sensor (DTS) generates a measurement result that indicates
directly the current temperature. The result of the measurement can be read via an DTS
register.
2.3.5
General Purpose I/O Ports and Peripheral I/O Lines
The TC1767 includes a flexible Ports structure with the following features:
Features
• Digital General-Purpose Input/Output (GPIO) port lines
• Input/output functionality individually programmable for each port line
• Programmable input characteristics (pull-up, pull-down, no pull device)
• Programmable output driver strength for EMI minimization (weak, medium, strong)
• Programmable output characteristics (push-pull, open drain)
• Programmable alternate output functions
• Output lines of each port can be updated port-wise or set/reset/toggled bit-wise
