Clock Control Register (Clkctr) 0Xe020 - Toshiba TX49 TMPR4937 Manual

5.2.5 Clock Control Register (CLKCTR)
Bit 32 and bits 15-0 are reset bits for the on-chip peripheral modules. To bring on-chip peripheral
modules out of the reset state, the corresponding bits must be cleared by software. Before clearing them,
wait at least 128 CPU clock cycles after they are set.
