Remark: This chapter describes parts LPC1850/30/20/10 Rev ‘A’ and parts LPC18xx
(with on-chip flash). For a description of the SCU for parts LPC1850/30/20/10 Rev ‘-’, see
Section
The following peripherals are not available on all parts, and the corresponding bit values
that select those functions in the SFSP registers are reserved:
The SCU is configured as follows:
Table 108. SCU clocking and power control
The system control unit determines the function and electrical mode of the digital pins. By
default function 0 is selected for all pins with pull-up enabled.
Remark: Analog I/Os for the ADCs and the DAC as well as several USB functions reside
on separate pins and are not controlled through the SCU.
The FUNC bits in the SFSX_Y registers control the function of each pin. If the function is
GPIO, the GPIOnDIR registers determine whether the pin is configured as an input or
output (see
automatically depending on the pin’s functionality. The GPIOnDIR registers have no effect
for peripheral functions.
The MODE bits in the SFSX_Y registers allow the selection of on-chip pull-up or pull-down
resistors for each pin or select the repeater mode.
