The user break address register (UBAR) consists of two registers: user break address register H

UBARH specifies the upper bits (bits 31 to 16) of the address for the break condition, while
UBARL specifies the lower bits (bits 15 to 0). The initial value of UBAR is H'00000000.

• UBARL Bits 15 to 0: specifies user break address 15 to 0 (UBA15 to UBA0)
