User manual
9.5.3 GPIO port output Clear register FIOxCLR (FIO0CLR to FIO4CLR-
0x2009 C01C to 0x2009 C09C)
This register is used to produce a LOW level output at port pins configured as GPIO in an
OUTPUT mode. Writing 1 produces a LOW level at the corresponding port pin and clears
the corresponding bit in the FIOxSET register. Writing 0 has no effect. If any pin is
configured as an input or a secondary function, writing to FIOxCLR has no effect.
Access to a port pin via the FIOxCLR register is conditioned by the corresponding bit of
the FIOxMASK register (see
Table 107. Fast GPIO port output Clear register (FIO0CLR to FIO4CLR- addresses 0x2009
Aside from the 32-bit long and word only accessible FIOxCLR register, every fast GPIO
port can also be controlled via several byte and half-word accessible registers listed in
Table
additional registers allow easier and faster access to the physical port pins.
