The functional port pins are listed in Table 7. The following pad types are available for system pins and functional port pins:

•

S — Slow (pad_ssr, pad_ssr_hv)

•

M — Medium (pad_msr, pad_msr_hv)

•

F — Fast (pad_fc)

•

J — Input/output with analog features (pad_tgate, pad_tgate_hv)

•

Analog — Input only with analog features (pad_ae, pad_ae_hv)

•

SMD — Stepper Motor Detector

•

DDR — DDR pads

•

RSDS — RSDS pads
