Field Description
SMC Safe Mode Control
This bit supports the overriding of the automatic deactivation of the output buffer of the associated
pad upon entering Safe mode of the SoC.
0 In SoC Safe mode, the output buffer of the pad is disabled.
1 In SoC Safe mode, the output buffer remains functional.
APC Analog Pad Control
This bit enables the usage of the pad as analog input.
0 Analog input path from the pad is gated and cannot be used.
1 Analog input path switch can be enabled by the ADC.
PA[1:0] Pad Output Assignment
This field is used to select the function that is allowed to drive the output of a multiplexed pad.
00 Alternative Mode 0: GPIO.
01 Alternative Mode 1: see Chapter 3, Signal Description
10 Alternative Mode 2: see Chapter 3, Signal Description
11 Alternative Mode 3: see Chapter 3, Signal Description
Note: Number of bit depending of the number of actual alternate function. Please refer to the
MPC5606S Microcontroller Data Sheet.
OBE Output Buffer Enable
This bit enables the output buffer of the pad in case the pad is in GPIO mode.
0 Output Buffer of the pad is disabled when PA = 00.
1 Output Buffer of the pad is enabled when PA = 00.
IBE Input Buffer Enable
This bit enables the input buffer of the pad.
0 Input Buffer of the pad is disabled.
1 Input Buffer of the pad is enabled.
ODE Open Drain Output Enable
This bit controls output driver configuration for the pads connected to this signal. Either open drain
or push/pull driver configurations can be selected. This feature applies to output pads only.
0 Open drain enable signal is negated for the pad.
1 Open drain enable signal is asserted for the pad.
