Port type B
This port type holds for pins that only work in input mode. Pins of port type B
are used for the corresponding alternative input function. At the same time, the
pin status can also be read via the port register Pn, so that the pin also works
in port function.
Block diagram: port type B
This section provides an overview of the port groups (Table 2-18, Table 2-19)
and of the pin functions (Table 2-20 on page 65). In Table 2-58 on page 97 it is
listed how the pin functions change if the microcontroller is reset or if it is in
one of the standby modes.
In the subsections, for every port group the settings of the configuration
registers is listed. Further, the addresses and initial values of the configuration
registers are given. See “Port group 0“ on page 72 to “Port group 13“ on
page 91.
Following tables provide overviews of the functions available at each port pin:
• Table 2-18 for µPD70(F)3420, µPD70(F)3421, µPD70(F)3422,
• Table 2-19 for µPD70F3424, µPD70F3425, µPD70F3426, µPD70F3427
