10.11.26 SCCR1 – Symbol Counter Control Register 1
8266B-MCU Wireless-03/11
feature works only if the symbol counter module operates with the 16 MHz clock from
XTAL1. After switching to RTC clock source, the symbol period synchronization is lost.
This bit is cleared automatically.
• Bit 6 – SCMBTS - Manual Beacon Timestamp
With this bit a manual beacon timestamp can be generated. If set to 1, the current
symbol counter value is stored into the beacon timestamp register. The bit is cleared
afterwards. The manual beacon timestamping can be used in conjunction with the
relative compare mode of the three compare units to generate compare match
interrupts without having a beacon frame received.
• Bit 5 – SCEN - Symbol Counter enable
This bit activates the symbol counter module. If the bit is not set, the counter, backoff
slot counter and the compare unit are disabled and disconnected from the clock. In this
way the power consumption can be reduced. All registers can be accessed, but write
access to the counter register SCCNT is not possible.
• Bit 4 – SCCKSEL - Symbol Counter Clock Source select
With this bit the clock source for the symbol counter can be selected. If the bit is one,
the RTC clock from TOSC1 is selected, otherwise the symbol counter operates with the
clock from XTAL1. During transceiver sleep modes the clock falls back to the RTC clock
source, regardless of the selected clock. After wakeup, it switches back to the previosly
selected clock source.
• Bit 3 – SCTSE - Symbol Counter Automatic Timestamping enable
This bit enables automatic SFD and Beacon Timestamping. If the bit is zero, no
automatic timestamp capturing is possible. Only manual beacon timestamping can be
used.
• Bit 2 – SCCMP3 - Symbol Counter Compare Unit 3 Mode select
This bit enables the relative compare mode for compare unit 3. If enabled, the counter
value is compared against the content of the beacon timestamp register plus the
content of the compare register 3 (SCCNT == SCBTS+SCOCR3). Otherwise, the
counter is compared against the copare register 3 (SCCNT == SCOCR3).
• Bit 1 – SCCMP2 - Symbol Counter Compare Unit 2 Mode select
This bit enables the relative compare mode for compare unit 2. If enabled, the counter
value is compared against the content of the beacon timestamp register plus the
content of the compare register 2 (SCCNT == SCBTS+SCOCR2). Otherwise, the
counter is compared against the copare register 2 (SCCNT == SCOCR2).
• Bit 0 – SCCMP1 - Symbol Counter Compare Unit 1 Mode select
This bit enables the relative compare mode for compare unit 1. If enabled, the counter
value is compared against the content of the beacon timestamp register plus the
content of the compare register 1 (SCCNT == SCBTS+SCOCR1). Otherwise, the
counter is compared against the copare register 1 (SCCNT == SCOCR1).
