TC290 / TC297 / TC298 / TC299 BB-Step
Package and Pinning DefinitionsTC299x Pin Definition and Functions:
• 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)

1) Pull-down with I_PORST relevant is always activated when a primary supply monitor detects a violation.
2) Valid additionally after deactivation of PORST until the internal reset phase has finished. See the SCU chapter for details.
3) See the SCU_IOCR register description.
4) Depends on JTAG/DAP selection with TRST.
In case of leakage test (PORST = 0 and TESTMODE = 0), the pull-down of the TRST pin is switched off. In case
of an user application (TESTMODE = 1), the pull-down of the TRST is always switched on.
