Function

Pull-down resistor of TEST/SBWTCK pin

Description

The device's internal pull-down resistor on the TEST/SBWTCK pin gets disabled if the SYS control bit SFRRPCR.SYSRSTRE is cleared. This can lead to increased current consumption and unintentionally-enabled JTAG access to the device.

Workaround

1) Do not clear the SFRRPCR.SYSRSTRE bit, use the SFRRPCR.SYSRSTRUP bit to define direction of the internal resistor on RST/NMI/SBWTDIO pin instead.

OR

2) Ensure a zero voltage level of TEST/SBWTCK pin by connecting the pin to an external component (e.g. external pull-down resistor) on the PCB.
