7.4.107 CONTEXT_CONF [51:37]  
CONTEXT_CONF is an array of 15 bytes, each controlling the configuration of the relevant ID, starting
with ID #1 associated to CONTEXT_CONF[37] up to ID #15 associated to CONTEXT_CONF[51].
Context ID #0 is reserved for context-less operation and has no configuration register.
Each configuration register holds the following format:
Table 181 — CONTEXT_CONF configuration format
Bit 7   Bit 6   Bit 5   Bit 4   Bit 3   Bit 2   Bit 1   Bit 0  
Reliability Mode  Large Unit Multiplier  Large Unit
Context
Config direction and
activate




Bit[7:6]: Reliability mode
0x0: MODE0 (normal)
0x1: MODE1 (non-Large Unit, reliable mode or Large Unit unit-by-unit mode)
0x2: MODE2 (Large Unit, one-unit-tail mode)
0x3: Reserved
Bit[5:3]: Large Unit multiplier
If Large Unit context is set, then the unit is multiplied by (Bit[5:3] + 1),
else it is ignored
Bit[2]: Large Unit context
0x0: Context is not following Large Unit rules
0x1: Context follows Large Unit rules
Bit [1:0]: Activation and direction selection
00b: Context is closed and is no longer active
01b: Context is configured and activated as a write-only context and according to the rest of the
bits in this configuration register
10b: Context is configured and activated as a read-only context and according to the rest of the
bits in this configuration register
11b: Context is configured and activated as a read/write context and according to the rest of the
bits in this configuration register
【 在 melongod (melongod) 的大作中提到: 】
: 扩展寄存器中有一段CONTEXT_CONF[51:37]，这15个byte里面所存的信息是用来配置什么的呢？在哪个或哪些手册里有明确的解释？
: 我看EmmC协议里的描述不是很明确，网上又查不到。
: 多谢大神！
