2.5.1.24 Memory Hardware Initialization Status Register (MINISTAT)
The MINISTAT register, shown in Figure 2-31 and described in Table 2-43, indicates the status of
hardware memory initialization.

Bit Field Value Description
31-0 MIDONE Memory hardware initialization status bit.
0 Read: Memory module[31-0] hardware initialization is not completed.
Write: A write of 0 has no effect.
1 Read: Memory module[31-0] hardware initialization is completed.
Write: The bit is cleared to 0.
Note: Disabling the MINITGENA key (by writing from a Ah to any other value) will reset all the
individual status bits to 0.
2.5.1.25 PLL Control Register 1 (PLLCTL1)
The PLLCTL1 register, shown in Figure 2-32 and described in Table 2-44, controls the output frequency of
PLL1 (Clock Source 1 - FMzPLL). It also controls the behavior of the device if a PLL slip or oscillator
failure is detected.
