Community Translation: TRAVEO™ T2G マイコン: デバッグ・インターフェイスのピン設定 – KBA236293

Version: **

After reset, the debug pins remain in a high-impedance (High-Z) state, and after the boot process, the debug pins are configured as follows:

Pin name

Input enable

Drive mode

swj_trstn

Yes

Internal pull-up

swj_swo_tdo

Yes

Strong (output)

swj_swdoe_tdi

Yes

Internal pull-up

swj_swdio_tms

Yes

Internal pull-up

swj_swclk_tclk

Yes

Internal pull-down

 
Note: For the swj_swo_tdo pin, the user application should either disable the input buffer or keep it enabled with the TDO line controlled through pull-up/pull-down. In general, an enabled input buffer for a floating line can draw a higher current.
 
Note: The debug access port pin may not be set in the boot process depending on the debug access port configuration in access restriction. For more details, see the application note AN228680 - Secure system configuration in TRAVEO™ T2G family.
 
Note: This KBA applies to the following series of TRAVEO™ T2G MCUs:
  • TRAVEO™ T2G CYT2 series
  • TRAVEO™ T2G CYT3 series
  • TRAVEO™ T2G CYT4 series
