Package and Pinning DefinitionsTC29x Bare Die Pad Definition
• Standard Pad Opening is 70um x 75um where 70um is the width of the opening (width as seen from the die
side) and 75um is the depth of the opening (from the die side into the silicon).
• Double Pad or Elephant Pad Opening is 130um x 75um where 130um is the width of the opening (width as
seen from the die side) and 75um is the depth of the opening (from the die side into the silicon). Double Pads
are used only for supply and can be identified by the words ´Double Pad´ or ´Elephant Pad´ in the Comment
column.
2.4.2 Emergency Stop Function
The Emergency Stop function can be used to force GPIOs (General Purpose Inputs/Outputs) via an external input
signal (EMGSTOPA or EMGSTOPB) into a defined state:
• Input state and
• PU or HighZ depending on HWCFG[6] level latched during Porst active
Control of the Emergency Stop function:
• The Emergency Stop function can be enabled/disabled in the SCU (see chapter “SCU”, “Emergency Stop
Control”)
• The Emergency Stop input signal, EMGSTOPA (P33.8) / EMGSTOPB (P21.2) , can selected in the SCU (see
chapter “SCU”, “Emergency Stop Control”)
• On port level, each GPIO can be enabled/disabled for the Emergency Stop function via the Px_ESR (Port x
Emergency Stop) registers in the port control logic (see chapter “General Purpose I/O Ports and Peripheral I/O
Lines”, “Emergency Stop Register”).
The Emergency Stop function is available for all GPIO Ports with the following exceptions:
• Not available for P20.2 (General Purpose Input/GPI only, overlayed with Testmode)
• Not available for P40.x (analoge input ANx overlayed with GPI)
• Not available for P32.0 EVR13 SMPS mode.
• Not available for dedicated I/O without General Purpose Output function (e.g ESRx, TMS, TCK)
The Emergency Stop function can be overruled on the following GPIO Ports:
• P00.x and P02.x: Emergency Stop can be overruled by the 8-Bit Standby Controller (SBR), if implemented.
Overruling can be disabled via the control registers P00_SCR / P02_SCR (see chapter “General Purpose I/O
Ports and Peripheral I/O Lines”, P00 / P01)
• P00.x: Emergency Stop can be overruled by the VADC. Overruling can be disabled via the control register
P00_SCR (see chapter “General Purpose I/O Ports and Peripheral I/O Lines”, P00)
• P14.0 and P14.1: Emergency Stop can be overruled in the DXCPL mode (DAP over can physical layer mode).
No Overruling in the DXCM (Debug over can message) mode
• P21.6: Emergency Stop can be overruled in JTAG mode if this pin is used as TDI
• P21.7: Emergency Stop can be overruled in JTAG or Three Pin DAP mode
• P20.0: Emergency Stop can be overruled in JTAG mode if this GPIO is used as TDI
• P33.8: Emergency Stop can be overruled if this pin is used as safety output pin (SMUFSP)
