5.15.2.1 MMC_HL_HWINFO Register

15.2.1.1 MMC_HL_HWINFO Register (Offset = 4h) [reset = 8h]

Information about the IP module's hardware configuration, i.e. typically the module's HDL generics (if any).
Actual field format and encoding is up to the module's designer to decide.

Table 5-1765 MMC_HL_HWINFO Register Field Descriptions

Bit	Field	Type	Reset	Description
31:7	RESERVED	R	0h
6	RETMODE	R	0h	Retention Mode generic parameter This bit field indicates whether the retention mode is supported using the pin PIRFFRET. 1 Retention mode enabled 0 Retention mode disabled
5:2	MEM_SIZE	R	2h	Memory size for FIFO buffer: 8 Memory of 4096 bytes, max block length is 2048 bytes 4 Memory of 2048 bytes, max block length is 2048 bytes 2 Memory of 1024 bytes, max block length is 1024 bytes 1 Memory of 512 bytes, max block length is 512 bytes
1	MERGE_MEM	R	0h	Memory merged for FIFO buffer: This register defines the configuration of FIFO buffer architecture. If the bit is set STA and DFT shall support clock multiplexing and balancing. 1 A single memory is used with multiplexed addresses, data and clocks. 0 2 memories instantiated, one per data transfer direction.
0	MADMA_EN	R	0h	Master DMA enabled generic parameter: This register defines the configuration of the controller to know if it supports the master DMA management called ADMA. 1 Controller supports ADMA 0 No Master DMA (ADMA) management supported
