4.2.93 RCGCI2C Register (Offset = 0x620) [reset = 0x00]
Inter-Integrated Circuit Run Mode Clock Gating Control (RCGCI2C)
The RCGCI2C register lets software enable and disable the I2C modules in run mode. When enabled, a module is provided a clock, and accesses to module registers are allowed. When disabled, the clock is disabled to save power, and accesses to module registers generate a bus fault.
NOTE
This register controls the clocking for the I2C modules.
RCGCI2C is shown in Figure 4-99 and described in Table 4-106.
