3.2.3 E-Ray register start address
The E-Ray register start address of the emulation system (MB9 MB88121B) is:
0x50.0000
. By
MB91F465XA series the E-Ray register address starts from
0x00.D000
.
Fujitsu provides two different header files for them.
1.
mb91465x.h
: for MB91F465XA series
2.
mb91465x_emulation.h
: for emulation system (MB9 MB88121B)
For further details refer to MB91460A series Hardware Manual and MB91F465XA series
Datasheet.
3.2.4 E-Ray IP version
The MB91F465XA is using E-Ray IP version
1.0
The MB88121B is using E-Ray IP version
1.0RC1
For further details refer to MB88121 and MB91F465XA series Datasheet.
3.2.5 CIF0 (CUST0) register value (Customer Register)
The value of register CIF0 (address: 0x00D000) by MB91F465XA series:
0x04FF.5BFF
The value of register CIF0 (address: 0x500000) by MB88121B:
0x0430.79FF
For further details refer to MB88121 and MB91F465XA series Datasheet.
3.2.6 CREL register value (Core Release Register)
The value of register CREL (address: 0x00D3F0) by MB91F465XA series:
0x1006.0519
The value of register CREL (address: 0x5003F0) by MB88121B:
0x0726.0412
The CREL register might be used by software to identify the used E-Ray IP version. The
software should be aware of the emulation system value.
For further details refer to MB88121 and MB91F465XA series Datasheet.
3.2.7 E-Ray clock control register
The FlexRay communication controller works on an internal clock frequency of 80MHz. In
order to achieve this, a PLL needs to be set.
Emulation System (MB9
MB88121B):
The CIF1 (address: 0x500004) register specifies the PLL settings for MB88121B.
MB91F465XA series:
The internal FlexRay CC uses a separate PLL (PLL2). The PLL2 registers (pll2divm,
pll2divn, pll2divg, pll2mulg, pll2ctrl, pll2clkr2) control the FlexRay PLL.
For further details refer to MB88121 and MB91F465XA series Datasheet.
