All input buffers are 5V tolerant LVTTL with the exception of RESET, Z_CTS,Z_DSR, Z_DCD and Z_RI which are Schmitt triggered
LVTTL, and XTLI which is LVTTL but not 5V tolerant.
All output buffers are 4 mA drive capability, with the exception of the EEPROM signals, Z_IOIS16, Z_IREQ and the UART output
signals which are all 2 mA drive capability.
Divider ratio of 1. These are sample measured figures.
