GIO Control Registers

25.5.1 GIO Global Control Register (GIOGCR0)

The GIOGCR0 register contains one bit that controls the module reset status. Writing a zero (0) to this bit

puts the module in a reset state. After system reset, this bit must be set to 1 before normal operations can

begin on this module. Figure 25-5 and Table 25-2 describe this register.
