TC1736
Introduction
2.4.5
General Purpose I/O Ports and Peripheral I/O Lines
The TC1736 includes a flexible Ports structure with the following features:
Features
• 70 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
2.4.6 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 TC1736, 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.
• The Boot ROM interface.
• The Emulation Memory interface.
• The Local Memory Bus LMB slave interface.
Following memories are controlled by and belong to the PMU0:
• 1 Mbyte of Program Flash memory (PFlash)
• 32 Kbyte of Data Flash memory (DFlash, represents 8 Kbyte EEPROM)
• 16 Kbyte of Boot ROM (BROM)
• 4 Kbyte Overlay RAM (OVRAM)
