RTCC FUNCTIONALITY

RTCC REGISTER MAP
The RTCC register space runs from 0x00 through to
0x1F. Any read or write that is started within the RTCC
register address space will wrap to the beginning of
the RTCC registers.
All of the RTCC registers are backed up from the VBAT
supply when VCC is not available, provided that the
VBATEN bit is set. Any unused bits or non imple-
mented addresses read back as ‘0’. No error checking
is provided for any of the RTCC, the user may load
any value.
The RTCC register map is shown in Table 4-1.
