VMEchip2 ID Register
This register is the VMEchip2 ID register. The ID for the VMEchip2 is 10.
VMEchip2 LM/SIG Register
This register is the VMEchip2 location monitor register and the interrupt
register.
SIG0 The SIG0 bit is set when a VMEbus master writes a 1 to
it. When the SIG0 bit is set, an interrupt is sent to the local
bus interrupter. The SIG0 bit is cleared when the local
processor writes a 1 to the SIG0 bit in this register or the
CSIG0 bit in the local interrupt clear register.
SIG1 The SIG1 bit is set when a VMEbus master writes a 1 to
it. When the SIG1 bit is set, an interrupt is sent to the local
bus interrupter. The SIG1 bit is cleared when the local
processor writes a 1 to the SIG1 bit in this register or the
CSIG1 bit in the local interrupt clear register.
SIG2 The SIG2 bit is set when a VMEbus master writes a 1 to
it. When the SIG2 bit is set, an interrupt is sent to the local
bus interrupter. The SIG2 bit is cleared when the local
processor writes a 1 to the SIG2 bit in this register or the
CSIG2 bit in the local interrupt clear register.
