general-purpose parallel IO-port. When used as a parallel port, it can be connected to circuits with a different
supply voltage.
Section 19.4 describes the basic functions of the LCD driver using the on-chip voltage generator. Section 19.5
describes more advanced the features of the LCD driver and especially different ways of generating the voltage for
the LCD. Section 19.6 describes how to use the peripheral as a general-purpose parallel IO-port. Section 19.7
shows how to partition when used as a partial LCD driver and partial IO port. Finally, the electrical specifications of
the driver are given in section 19.8.
19.3 Register map
There are thirty-six registers in the LCD driver, namely RegVgenCfg0, RegLcdOn, RegLcdSe, RegLcdClkFrame,
RegLcdDataN (0≤N≤15), RegPLcdInN (0≤N≤3), RegPLcdOutN (0≤N≤3), RegPLcdDirN (0≤N≤3) and
RegPLcdPullupN (0≤N≤3). Table 19-2 to Table 19-11 show the mapping of control bits and functionality of these
registers while Table 19-1 gives the default address of these thirty-six registers.
