NOTE:
1. If Port C is configured for word size, data can be written to the Mail2 register using C0-C17. In this first case, A18-A35 will have valid data (A0-A17 will be indeterminate). If Port C is configured
IDT723626/723636/723646 CMOS TRIPLE BUS SyncFIFO™
WITH BUS-MATCHING 256 x 36 x 2, 512 x 36 x 2 and 1,024 x 36 x 2
NOTE:
1. If Port B is configured for word size, data can be written to the Mail1 register using A0-A17 (A18-A35 are don't care inputs). In this first case B0-B17 will have valid data. If Port B is configured
C0-C17
B0-B17
for byte size, data can be written to the Mail2 register using C0-C8 (C9-C17 are don't care inputs). In this second case, A18-A26 will have valid data (A0-A17 and A27-A35 will be
indeterminate).
A0-A35
for byte size, data can be written to the Mail1 Register using A0-A8 (A9-A35 are don't care inputs). In this second case, B0-B8 will have valid data (B9-B17 will be indeterminate).
