The default GPIO settings for configuration mode 11 are shown below in Table 69.
Table 69 Default GPIO Settings for Configuration Mode 11
Note that setting GP4_CFG = 1 results in Active Low function for /MR. Also, 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.
