Table 7. LED Anode/GPIO Port A Output Control Register
These functions are memory-mapped with an address decoder based on
the Generic Array Logic GAL22lV10D (U15) device manufactured by
Lattice Semiconductor, and a bidirectional latch (U16). Additionally, U15
is used to decode addresses for access to the 7x5 LED matrix.
Table 6 lists the memory map addresses to registers that allow access to
the above functions. The register at address

data.
Port A Emulation
GPIO Port A is emulated with the use of the GPIO Output Control Regis-
ter and the GPIO Data Register. If bit 7 in the GPIO Output Control Reg-
ister is 1, all of the lines on GPIO Port A are configured as input ports. If
this bit is 0, all of the lines on Port A are configured as output ports.
Table 7 lists the multiple functions of the register.
