Pull-down and pull-up strength are provided as part of Table 13 in Section 3.6.1, I/O input DC characteristics.
Pull-up/Pull-down are activated within 2 µs after internal reset has been asserted. Actual pad transition will depend
on external capacitance.

Unlike ESR0, ESR1 is provided as normal GPIO and implements weak pull-up during power-up.

An internal pull-down is implemented on the TESTMODE pin to prevent the device from entering test mode if the
package TESTMODE pin is not connected. It is recommended to connect the TESTMODE pin to V
SS_HV_IO
on the
board for maximum robustness, but not required. The value of TESTMODE is latched at the negation of reset and
has no affect afterward. The device will not exit functional reset with the TESTMODE pin asserted during power-up.
The TESTMODE pin can be connected externally directly to ground without any other components.
