Status Register
Status Register (ADR 8)
4689B–RKE–04/04
The status register indicates the current status of the transceiver and is readable via the
4-wire serial interface. Setting Power_On or P_On_Aux or an event on ST1, ST2, ST3,
ST4 or ST5 is indicated by an IRQ.
Reading the status register resets the bits Power_On, Low_Batt, P_On_Aux and the
IRQ

Function
Status of pin T5
Pin T5 = 0
Pin T5 = 1
(see Figure 29 on page 41)
Status of pin T4
Pin T4 = 0
Pin T4 = 1
(see Figure 29 on page 41)
Status of pin T3
Pin T3 = 0
Pin T3 = 1
(see Figure 29 on page 41)
Status of pin T2
Pin T2 = 0
Pin T2 = 1
(see Figure 29 on page 41)
Status of pin T1
Pin T1 = 0
Pin T1 = 1
(see Figure 29 on page 41)
Indicates that the transceiver was woken up by pin PWR_ON (rising edge on pin
PWR_ON). During Power_On = 1, the bits VSOUT_EN and CLK_ON in control
register 3 are set to 1.
(see Figure 30 on page 42)
Indicates that output voltage on pin VSOUT is too low
(V
(see Figure 31 on page 43)
Indicates that the auxiliary supply voltage on pin VAUX is high enough to operate.
State transition:
a) OFF mode
b) Idle mode (VSOUT = VS1)
