MODCK_H is a 3-bit field that occupies bits 28–30 of the Hard Reset Configuration Word. The bits are listed
in the table in the following order: bit 28, bit 29, bit 30. For example, the value 110 indicates that bit 28 = 1,
bit 29 = 1, and bit 30 = 0.
MODCK[1–3] are external signal inputs that are either pulled up (1) or pulled down (0) to configure the
system clock mode. The values are listed in the table in the following order: MODCK1, MODCK2, MODCK3.
For example, the value 110 indicates that MODCK1 is pulled up, MODCK2 is pulled up, and MODCK3 is
pulled down.
