Table 26.2-2 Function of Each Bit of PACSR1 and PACSR0
Bit name Function
bit15, bit14 Reserved bits Bit15, bit14 are reserved. Set these bits to "0" before setting PACSR1.
bit13
AD5E:
Address detect
register 1 enable The AD5E bit is the operation permission bit for PADR5.
When this bit is "1", the address is compared with the PADR5 register. If they match,
the INT9 instruction is issued.
bit12 Reserved bit Bit12 is reserved. Set this bit to "0" before setting PACSR1.
bit11
AD4E:
Address detect
register 1 enable The AD4E bit is the operation permission bit for PADR4.
When this bit is "1", the address is compared with the PADR4 register. If they match,
the INT9 instruction is issued.
bit10 Reserved bit Bit10 is reserved. Set this bit to "0" before setting PACSR1.
bit9
AD3E:
Address detect
register 1 enable The AD3E bit is the operation permission bit for PADR3.
When this bit is "1", the address is compared with the PADR3 register. If they match,
the INT9 instruction is issued.
bit8 Reserved bit Bit8 is reserved. Set this bit to "0" before setting PACSR1.
bit7 to bit4 Reserved bits Bit7 to bit4 are reserved. Set these bits to "0" before setting PACSR0.
bit3
AD1E:
Address detect
register 1 enable The AD1E bit is the operation permission bit for PADR1.
When this bit is "1", the address is compared with the PADR1 register. If they match,
the INT9 instruction is issued.
bit2 Reserved bit Bit2 is reserved. Set this bit to "0" before setting PACSR0.
bit1
AD0E:
Address detect
register 0 enable The AD0E bit is the operation permission bit for PADR0.
When this bit is "1", the address is compared with the PADR0 register. If they match,
the INT9 instruction is issued.
