Si1010/1/2/3/4/5
RTC0DAT until the next read or write operation. Below is an example of reading a SmaRTClock internal
register.
1. Poll BUSY (RTC0ADR.7) until it returns 0 or follow recommended instruction timing.
2. Write 0x05 to RTC0ADR. This selects the internal RTC0CN register at SmaRTClock Address 0x05.
3. Write 1 to BUSY. This initiates the transfer of data from RTC0CN to RTC0DAT.
4. Poll BUSY (RTC0ADR.7) until it returns 0 or follow recommend instruction timing.
5. Read data from RTC0DAT. This data is a copy of the RTC0CN register.
Note: The RTC0ADR and RTC0DAT registers will retain their state upon a device reset.
20.1.3. RTC0ADR Short Strobe Feature
Reads and writes to indirect SmaRTClock registers normally take 7 system clock cycles. To minimize the
indirect register access time, the Short Strobe feature decreases the read and write access time to 6 sys-
tem clocks. The Short Strobe feature is automatically enabled on reset and can be manually enabled/dis-
abled using the SHORT (RTC0ADR.4) control bit.
Recommended Instruction Timing for a single register read with short strobe enabled:
mov RTC0ADR, #095h
nop
nop
nop
mov A, RTC0DAT
Recommended Instruction Timing for a single register write with short strobe enabled:
mov RTC0ADR, #095h
mov RTC0DAT, #000h
nop
20.1.4. SmaRTClock Interface Autoread Feature
When Autoread is enabled, each read from RTC0DAT initiates the next indirect read operation on the
SmaRTClock internal register selected by RTC0ADR. Software should set the BUSY bit once at the begin-
ning of each series of consecutive reads. Software should follow recommended instruction timing or check
if the SmaRTClock Interface is busy prior to reading RTC0DAT. Autoread is enabled by setting AUTORD
(RTC0ADR.6) to logic 1.
