Device registers
There are five different registers within the device interface:
These registers are used for the serial data communication and can be accessed only using
the corresponding commands (refer to section 7.9 of the JEDEC Standard Specification No.
JESD84-A43. The device does not implement the DSR register.
The MultiMediaCard has a status register to provide information about the device current
state and completion codes for the last host command.
Operation conditions register (OCR)
The 32-bit operation conditions register stores the V
flash memory component. The device is capable of communicating (identification procedure
and data transfer) with any MultiMediaCard host using any operating voltage within 1.7 V
and 1.95 V (low-voltage range) or 2.7 V and 3.6 V (high-voltage range) depending on the
voltage range supported by the host. For further details, refer to section 8.1 of the JEDEC
Standard Specification No. JESD84-A43.
If the host tries to change the OCR values during an initialization procedure the changes in
the OCR content will be ignored.
The level coding of the OCR register is as follows:
Table 6.
1. This bit is set to Low if the device has not finished the power-up routine.
