NOTES:

 

 

 

 

 

 

 

 

 

 

 

1.The PortE output buffer enable signal control at reset is determined by the PEAR register and is mode dependent. E.g. in special test mode RDWE=LSTRE=1 which enables the PE[3:2] output buffers and disables the pull-ups. Refer to S12_MEBI user guide for PEAR register details.

2.CAN functionality is not available on the MC9S12GC-Family members

2.2.1 Pin Initialization for 48 & 52 Pin LQFP bond-out versions

Not Bonded Pins If the port pins are not bonded out in the chosen package the user should initialize the registers to be inputs with enabled pull resistance to avoid excess current consumption. This applies to the following pins:

(48LQFP): Port A[7:1], Port B[7:5], Port B[3:0], PortE[6,5,3,2], Port P[7:6], PortP[4:0], Port J[7:6], PortS[3:2]

(52LQFP): Port A[7:3], Port B[7:5], Port B[3:0], PortE[6,5,3,2], Port P[7:6], PortP[2:0], Port J[7:6], PortS[3:2]
