NOTES:
1 The PDSR and PSSR registers are described in the Ports/GPIO chapter of the MCF5213 Reference Manual. All programmable signals default to 2mA drive
and FAST slew rate in normal (single-chip) mode.
2 All signals have a pull-up in GPIO mode.
3 The multiplexed CANTX and CANRX signals are not available on the MCF5211 or MCF5212
4 For primary and GPIO functions only.
5 Only when JTAG mode is enabled.
6 CLKMOD0 and CLKMOD1 have internal pull-down resistors, however the use of external resistors is very strongly recommended
7 For secondary and GPIO functions only.
8 RSTI has an internal pull-up resistor, however the use of an external resistor is very strongly recommended
9 For GPIO function. Primary Function has pull-up control within the GPT module
10 CANTX and CANRX are secondary functions only.
