Real-Time Clock
The real-time clock unit of the C505L contains a dedicated oscillator and a 47-bit timer which is used
to count time elapsed with respect to an initial time. The C505L real-time clock does not provide for
any error correction. Any such corrections can be done by software only.
Functionality
The real-time clock can be initialized to a 40-bit initial value, which are loaded into the upper 40-bits
of the timer. The lower 7 bits of the counter are never accessible by the user and merely act as
prescalers that are initialized to 0000000
B
after a start operation on the real-time clock. One
increment of the clock register is made for every cycle of the input clock (32.768 kHz). The
functionality of the real-time clock is shown in
Figure 18
.

Real-Time Clock
The register memory for the real-time clock is implemented in the on-chip external data memory
area. Accesses to these registers are similar to on-chip XRAM accesses (MOVX instructions) and
therefore must be preceded by an enable operation on the on-chip XRAM. These registers include
the RTCON, RTCR0 to RTCR4 (RTCR), CLREG0 to CLREG4 (CLREG) and RTINT0 to RTINT4
(RTINT) registers.
