RD_RTC_STATE
This command reads out the update status of the RTC
ONCE: a “1” indicates RTC data has been updated at least once
CURR-SYNC: a “1” indicates RTC data has just been correctly synchronized with RC time,
once this bit has been read, this bit will reset to “0”.
27-SYNC: a “1” indicates RTC data has been synchronized with RC time within 27 hours.
RD_TIME
SET_RX_CTRL
This command sets the receiver module to a predefined state of reception during auto
and manual reception: either single band, dual band or triple band reception.
The mode of reception is defined by the bits 0 to 2.
AUTO : If this bit is set as 1, the module will go into reception automatically according
to auto reception time set in SET_RX_DUR for duration CMD_RX_INT, and mode as
set in bits 0 to 2. If bit is 0, there will be no auto radio control reception as if radio
control function is off.
FCE : If this bit is set as 1, the module will go into reception immediately according to
mode as set in bits 0 to 2 for maximum duration as set in SET_RX_DUR.
CANCEL: If this bits is set as 1, the module will stop reception immediately if reception
is in process.
C0,C1 : sets the number of auto receptions per day .
Revision
B6
00 – there will be no auto receptions
01 – there will be 1 auto reception per day
10 – there will be 2 auto receptions per day
11 – there will be 3 auto receptions per day
