Function: Read MIFARE 1K/4K one block data.

Host sends:

Frame 0x21 Key ID Block Key Checksum

Key ID: 1 byte, Key identifier

BIT0 = 0: Key A; BIT0 = 1: Key B;

BIT1=0: using the key in the command; BIT1=1: using the key downloaded by

command 0x2D;

BIT6:BIT5:BIT4:BIT3:BIT2: if use the downloaded key, this is the index of the key;

BIT7=0: The block need to be certified via using the above key;

BIT7=1: The block has been authenticated and passed. Do not need authentication

again. (This operation and automatic detecting card could not be used at the same

time);

(IMPORTANT: more information please refers to Chapter 5.3 about Key identifier).

Block: 1 byte, Block number to read, 0 to 0x3F for S50; 0 to 0xFF for S70;
