UBAMRL:
The user break address mask register (UBAMR) consists of user break address mask register H
(UBAMRH) and user break address mask register L (UBAMRL). Both are 16-bit
readable/writable registers. UBAMRH designates whether to mask any of the break address bits
established in the UBARH, and UBAMRL designates whether to mask any of the break address
bits established in the UBARL. UBAMRH and UBAMRL are initialized by a power on reset to
H'0000. They are not initialized in software standby mode.
UBAMRH Bits 15 to 0—User Break Address Mask 31 to 16 (UBM31 to UBM16): These bits
designate whether to mask any of the break address 31 to 16 bits (UBA31 to UBA16) established
in the UBARH.
UBAMRL Bits 15 to 0—User Break Address Mask 15 to 0 (UBM15 to UBM0): These bits
designate whether to mask any of the break address 15 to 0 bits (UBA15 to UBA0) established in
the UBARL.
