LBAE:
= 0: Disable the interrupt on the INT pin when the LBAI bit (b1, T1/J1-07BH,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the LBAI bit (b1, T1/J1-07BH,...) is ‘1’.
LBDE:
= 0: Disable the interrupt on the INT pin when the LBDI bit (b0, T1/J1-07BH,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the LBDI bit (b0, T1/J1-07BH,...) is ‘1’.

LBAI:
= 0: There is no status change on the LBA bit (b1, T1/J1-077H,...).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the LBA bit (b1, T1/J1-077H,...).
This bit will be cleared if a ’1’ is written to it.
LBDI:
= 0: There is no status change on the LBD bit (b0, T1/J1-077H,...).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the LBD bit (b0, T1/J1-077H,...).
This bit will be cleared if a ’1’ is written to it.
