Lower Four Bits of IEBus Reception Master Address  
Indicates the lower four bits of the communication 
destination master unit address in slave/broadcast 
reception. This register is enabled when 
slave/broadcast reception starts, and the contents are 
changed at the time of setting the RXS flag. If a 
broadcast receive error interrupt is selected by the DEE 
bit in IECTR and the receive buffer is not in the receive 
enabled state at control field reception, a receive error 
interrupt is generated and the lower four bits of the 
master address are stored in IEMA1. 
3 to 0 
 All 
Reserved 
These bits are always read as 0. The write value should 
always be 0.
