TC1797_14 Datasheet, PDF (27/192 Pages) Infineon Technologies AG – 32-Bit Single-Chip Microcontroller

TC1797
Introduction
• Trigger sources that need a clock in order to be asserted, such as the input signals
ESR0, 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 TC1797 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
2.3.6 Program Memory Unit (PMU)
The devices of the AudoF family contain at least one Program Memory Unit. This is
named “PMU0”. Some devices contain additional PMUs which are named “PMU1”, …
In the TC1797, the PMU0 contains the following submodules:
• The Flash command and fetch control interface for Program Flash and Data Flash.
• The Overlay RAM interface with Online Data Acquisition (OLDA) support.
