The default GPIO settings for configuration mode 01 are shown below in Table 65.
Table 65 Default GPIO Settings for Configuration Mode 01
Note that setting GP11_CFG = 1 results in Active Low function for /WAKEUP. In most cases, setting
GPn_CFG = 1 results in Active High function, but /MR, /WAKEUP and /LDO_ENA are exceptions to
this. See Section 20.
