SPRS230L –OCTOBER 2003 –REVISED DECEMBER 2009

The user can select the type of input qualification for each GPIO pin via the GPxQSEL1/2 registers from four choices:

•Synchronization To SYSCLKOUT Only (GPxQSEL1/2 = 0,0): This is the default mode of all GPIO pins at reset and it simply synchronizes the input signal to the system clock (SYSCLKOUT).

•Qualification Using Sampling Window (GPxQSEL1/2 = 0,1 and 1,0): In this mode the input signal, after synchronization to the system clock (SYSCLKOUT), is qualified by a specified number of cycles before the input is allowed to change.

Figure 4-17. Qualification Using Sampling Window

•The sampling period is specified by the QUALPRD bits in the GPxCTRL register and is configurable in groups of 8 signals. It specifies a multiple of SYSCLKOUT cycles for sampling the input signal. The sampling window is either 3-samples or 6-samples wide and the output is only changed when ALL samples are the same (all 0s or all 1s) as shown in Figure 6-12(for 6 sample mode).

•No Synchronization (GPxQSEL1/2 = 1,1): This mode is used for peripherals where synchronization is not required (synchronization is performed within the peripheral).

Due to the multi-level multiplexing that is required on the 280x device, there may be cases where a peripheral input signal can be mapped to more then one GPIO pin. Also, when an input signal is not selected, the input signal will default to either a 0 or 1 state, depending on the peripheral.
