1 The PDSR and PSRR registers are described in the GPIO chapter of the MCF52110 Reference Manual. All programmable signals default to 2 mA drive and

FAST slew rate in normal (single-chip) mode.

2 All signals have a pull-up in GPIO mode.

3 For primary and GPIO functions only.

4 Only when JTAG mode is enabled.

5 CLKMOD0 and CLKMOD1 have internal pull-down resistors, however the use of external resistors is very strongly recommended

6 For secondary and GPIO functions only.

7 RSTI has an internal pull-up resistor, however the use of an external resistor is very strongly recommended

8 For GPIO function. Primary Function has pull-up control within the GPT module
