BARBH
BARBL
Break address register B (BARB) consists of two 16-bit readable/writable registers: break address
register BH (BARBH) and break address register BL (BARBL). BARBH specifies the upper half
(bits 31 to 16) of the address used as a channel B break condition, and BARBL specifies the lower
half (bits 15 to 0). BARBH and BARBL are initialized to H'0000 by a power-on reset; after a
manual reset, their values are undefined.
BARBH Bits 15 to 0—Break Address B31 to B16 (BAB31 to BAB16): These bits store the upper
half (bits 31 to 16) of the address used as a channel B break condition.
BARBL Bits 15 to 0—Break Address B15 to B0 (BAB15 to BAB0): These bits store the lower
half (bits 15 to 0) of the address used as a channel B break condition.
