1.3.4.27
PS3 and PS2 are general purpose input or output pins. These pins are not available in the 48- / 52-pin
package versions.
1.3.4.28
PS1 is a general purpose input or output pin and the transmit pin, TXD, of serial communication interface
(SCI).
1.3.4.29
PS0 is a general purpose input or output pin and the receive pin, RXD, of serial communication interface
(SCI).
1.3.4.30
PT7–PT5 are general purpose input or output pins. They can also be configured as the timer system input
capture or output compare pins IOC7-IOC5.
1.3.4.31
PT4–PT0 are general purpose input or output pins. They can also be configured as the timer system input
capture or output compare pins IOC[n] or as the PWM outputs PW[n].
1.3.5
1.3.5.1
External power and ground for I/O drivers. Bypass requirements depend on how heavily the MCU pins are
loaded.
1.3.5.2
External power and ground for the internal voltage regulator. Connecting V
internal voltage regulator.
1.3.5.3
Power is supplied to the MCU through V
regulator. There is no static load on those pins allowed. The internal voltage regulator is turned off, if V
is tied to ground.
