v138 v139 1025 1025 Some boards have a ''Tamper Detect'' circuit implemented either as a physical pushbutton on the board and/or a header that can have an external switch wired to it. The circuit implemented is a ''normally open'' switch to board ground (GND). 1026 1026 1027 For these boards you can enable the GSC's ''Tamper Detect'' feature by setting [#gsc_ctrl_0 TAMPER_DETECT (R0.5)] and the accompanying interrupt enable register bit [#gsc_interrupt_enable IRQ_TAMPER_DETECT (R11.5)]. Once these bits are set any tamper event produced by a switch closing and the signalconducting to board ground will do the following:1027 For these boards you can enable the GSC's ''Tamper Detect'' feature by setting [#gsc_ctrl_0 TAMPER_DETECT (R0.5)] and the accompanying interrupt enable register bit [#gsc_interrupt_enable IRQ_TAMPER_DETECT (R11.5)].
