Direct Memory Access Request. Active high
output requesting RTI access to memory.
Memory Clock (DMA Grant). Active low input
signaling the RTI that a memory access is
granted. Internal to the RTI, receipt of MEMCK
generates RAM chip select and RAM read/write
signals.
External Self-test Enable. Multi-function input
pin. In self-test mode forcing this pin high
allows the monitoring of self-test activity at the
bus stub. When the RTI is not in self-test this
pin defines the function of TALEN/PARITY.
External Self-test Channel Select. A/B Multi-
function input pin. In self-test mode forcing this
pin high selects the channel on which the self-
test is performed (Channel A = 1, Channel B =
0). When the RTI is not in self-test this pin
defines the function of TALEN/PARITY.
