(27) Baseband interrupt source register 1 (BBINTREQ1)
This register is used to indicate the baseband interrupt source.
A bit of this register indicates that “1” is set to the interrupt source corresponding to each interrupt
occurrence timing so that there is an interrupt request. When reading this register, only the bit from which 1
is read is cleared to 0. Note that perform the dummy read when you clear the bit because writing is disabled.
The BBINTREQ1 register consists of 8 bits and can be accessed (serial interface communication) in 8 bit
unit.
Note
Reset signal generation clears this register to 00H.
Note When reading this register, read 3 bytes of the baseband interrupt source registers 0 to 2
(BBINTREQ0 to BBINTREQ2) continuously (leave SEN internal pin low level).
