Selects the register page.
Table 69.
Table 70.
Shows the actual MSB and LSB values of the CRC calculation.
Note: The CRC is split into two 8-bit register.
Note: Setting the bit MSBFirst in ModeReg register reverses the bit order, the byte order is
not changed.

Description
and A4. The LSB-bits of the register address are defined by the
address pins or the internal address latch, respectively.
Set to logic 0, the whole content of the internal address latch defines
the register address. The address pins are used as described in
Section 10.1 “Automatic host controller interface type
Reserved for future use.
The value of PageSelect is used only if UsePageSelect is set to
logic 1. In this case, it specifies the register page (which is A5 and
A4of the register address).
Description
This register shows the actual value of the most significant byte of
the CRCResultReg register. It is valid only if bit CRCReady in
register Status1Reg is set to logic 1.
