User manual
Writing to the IOPIN register stores the value in the port output register, bypassing the
need to use both the IOSET and IOCLR registers to obtain the entire written value. This
feature should be used carefully in an application since it affects the entire port.
Legacy registers are the IO0PIN and IO1PIN while the enhanced GPIOs are supported
via the FIO0PIN, FIO1PIN, FIO2PIN, FIO3PIN and FIO4PIN registers. Access to a port
pin via the FIOPIN register is conditioned by the corresponding bit of the FIOMASK
register (see
FIOMASK(FIO[0/1/2/3/4]MASK - 0x3FFF
Only pins masked with zeros in the Mask register (see
Mask register FIOMASK(FIO[0/1/2/3/4]MASK - 0x3FFF
correlated to the current content of the Fast GPIO port pin value register.
Table 170. GPIO port Pin value register (IO0PIN - address 0xE002 8000 and IO1PIN - address
Table 171. Fast GPIO port Pin value register (FIO[0/1/2/3/4]PIN - address
Aside from the 32-bit long and word only accessible FIOPIN 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.
