I/O RAM Map –Functional Order
In Table 74 and Table 75, unimplemented (U) and reserved (R) bits are shaded in light gray. Unimplemented bits are identified with a ‘U’.
Unimplemented bits have no memory storage, writing them has no effect, and reading them always returns zero. Reserved bits are identified with
an ‘R’, and must always be written with a zero. Writing values other than zero to reserved bits may have undesirable side effects and must be
avoided. Non-volatile bits are shaded in dark gray. Non-volatile bits are backed-up during power failures if the system includes a battery connected
to the VBAT pin.
The I/O RAM locations listed in Table 74 have sequential addresses to facilitate reading by the MPU (e.g., in order to verify their contents). These
I/O RAM locations are usually modified only at boot-up. The addresses shown in Table 74 are an alternative sequential address to the addresses
from Table 75 which are used throughout document. For instance, EQU[2:0] can be accessed at I/O RAM 0x2000[7:5] or at I/O RAM 0x2106[7:5].
