Motorola Interconnect Bus (MI BUS)
6.10.1 INIT2 — EEPROM mapping and MI BUS delay register
Technical Data
EEPROM mapping (INIT2)
This register sets the MI BUS delay time. INIT2 may be read at any time
but bits 7–4 may be written only once after reset in normal modes (bits
3–0 may be written at any time).
EE[3:0] — EEPROM map position
M3DL1:M3DL0, M2DL1:M2DL0 — MI BUS delay select
Freescale Semiconductor, Inc.
EEPROM is located at $xD80–$xFFF, where x is the hexadecimal
digit represented by EE[3:0]. Refer to
and MI BUS delay
These bits are used to set up the delay for the start of the NRZ receive
for MI BUS operation as shown (for a 20kHz bit rate) in the following
table. Each MI BUS module is controlled by one pair of bits.
