When a PMC MIO bank is powered at 3.3V or 2.5V and is used with a SelectMAP interface, MIO20 (RDWR_B) might affect data outputs of SelectMAP during SelectMAP read abort.
Additionally, assertion of SRST when using SYSMON I2C/PMBUS can result in MIO14 (data) and MIO21 (busy) getting into the tristate race condition when booting from SelectMap.
