Digital Inputs and Outputs
The input pulse width specification applies to any input signal which is sampled by a peripheral of the
chip. All inputs are clocked through synchroniser circuits to eliminate metastable data when reading
input registers.
Output signal rise and fall times depend on the external load on each signal and the drive current
capability of the output. Rise times are to 70% of VDD and fall times to 30% of VDD.

The following pins have 2mA output drive capability:
eICE_LOADB/JTMS, eICE_MISO/JTDO, nReset_Out.
The following pins have 2mA output drive capability and selectable internal pull-up resistors:
PortA_0-7, PortB_5-7, PortR_0-7, PortS_0-7, PortT_0-3.
The following pins have 2mA output drive capability, selectable internal pull-up resistors, and are 5V tolerant:
PortB_0-4, PortK_0-3, PortL_0-3, PortN_0-7, PortP_0-7, PortQ_0-7. The outputs must be disabled (tristated) or
used in open-drain mode when signals above VDD are present on these pins.
The following pins have 4mA output drive capability:
PortC_0-3, PortD_0-3, PortE_0-7, PortF_0-3, PortG_0-3, PortH_0-7, PortI_0-7, PortJ_0-3, PortM_0-7.
