36 / 129 page  PSoC® 3: CY8C38 Family Data Sheet Document Number: 001-11729 Rev. *R Page 36 of 129 6.4.1 Drive Modes Each GPIO and SIO pin is individually configurable into one of the eight drive modes listed in Table 6-6. Three configuration bits are used for each pin (DM[2:0]) and set in the PRTxDM[2:0] registers. Figure 6-11 depicts a simplified pin view based on each of the eight drive modes. Table 6-6 shows the I/O pin’s drive state based on the port data register value or digital array signal if bypass mode is selected. Note that the actual I/O pin voltage is determined by a combination of the selected drive mode and the load at the pin. For example, if a GPIO pin is configured for resistive pull-up mode and driven high while the pin is floating, the voltage measured at the pin is a high logic state. If the same GPIO pin is externally tied to ground then the voltage unmeasured at the pin is a low logic state. Figure 6-11. Drive Mode Table 6-6.
