CMOS TS Output, 2mA, 50K Pull Up
MBUS Write Enable, high byte. Asserted on writes to the high-order
byte of x16 memory devices that use the JEDEC 4-wire control
interface. Also asserted (as MA[0]) when accessing the odd (high-
order) byte of a word stored in a x8 memory device. During word
accesses of x8 memory, the odd byte is accessed first.
