Control bit description.
Single message transmission:
After completing the data transmission to the ASCell3911, the
μC may indicate ”end of transmission” by setting P4 (not end of transmit) to ”L” and pulls the
WAKEUP line to ”L”. Sensing this, 4 clock cycles later the ASCell3911 will switch the μC back to
standby mode, disabling the μC_CLK output, setting the active WAKEUP pin to ”L”. The AS-
Cell3911 will finish the transmission sequence and than turning off the XTAL oscillator to and
goes back to the standby mode too. The SMT/CMT bit is ”L” indicates the single transmission
mode.
Note: SMT/CMT is one bit of the control information.
Continuous message transmission:
After completing the data transmission to the AS-
Cell3911, the μC may indicate ”end of transmission” by setting P4 to ”L” and pulls the WAKEUP
line to ”L”. Sensing this, 4 clock cycles later the ASCell3911 will switch back to standby mode,
disabling the μC_CLK output, setting the active WAKEUP pin to ”L” and than turning off the XTAL
oscillator. The SMT/CMT bit is ”H” indicates the continuous transmission mode.
Note: SMT/CMT is one bit of the control information.
Due to the sophisticated tri-state - active/inactive pull-up configuration of the WAKEUP pin the
ASCell3911 does not drain current during its standby periods.
The interface implemented in the ASCell3911 system cell is a general, non-specialized example
only. It can be modified on customers demand.
