Section 7 User Break Controller (UBC)
7.3.6
BRCR sets the following conditions:
1. Specifies whether a start of user break interrupt exception processing by instruction fetch cycle
2. Specifies the pulse width of the UBCTRG output when a break condition is satisfied.
BRCR is a 32-bit readable/writable register that has break condition match flags and bits for
setting other break conditions. For the condition match flags of bits 15 to 12, writing 1 is invalid
(previous values are retained) and writing 0 is only possible. To clear the flag, write 0 to the flag
bit to be cleared and 1 to all other flag bits. BRCR is initialized to H'00000000 by a power-on
reset and in deep standby, but retains its previous value by a manual reset or in software standby
mode or sleep mode.

These bits are always read as 0. The write value
should always be 0.
Clock Select
Specifies the pulse width output to the UBCTRG pin
when a break condition is satisfied.
00: Pulse width of UBCTRG is one bus clock cycle
01: Pulse width of UBCTRG is two bus clock cycles
10: Pulse width of UBCTRG is four bus clock cycles
11: Pulse width of UBCTRG is eight bus clock cycles
