-#### Registers
+#### RFID Chip Registers
 
-```
-Writing 0x7F to the "ComIEnReg" means the following:
-
-    Bit 7: IRqInv=0 - Interrupts are active high
-    Bit 6: TxIEn=1 - Transmitter interrupt is enabled
-    Bit 5: RxIEn=1 - Receive interrupt is enabled
-    Bit 4: IdleIEn=1 - Idle interrupt is enabled
-    Bit 3: HiAlertIEn=1 - "High Alert" interrupt is enabled
-    Bit 2: LoAlertIEn=1 - "Low Alert" interrupt is enabled
-    Bit 1: ErrIEn=1 - Error interrupt is enabled
-    Bit 0: TimerIEn=1 - Timer interrupt is enabled
-
-The bits in the register "ComIrqReg" have the following meaning:
-
-    Bit 7: Set1 - when written as 1, a bit value of 1 in bits 6-0 of the byte written set the corresponding register bit; when written as 0, bits 6-0 clear the corresponding register bit
-    Bit 6: TxIRq - Set when the last bit of Tx data has been sent
-    Bit 5: RxIRq - Set when the receiver detects the end of a valid data stream
-    Bit 4: IdleIRq - Set when the CommandReg changes the command field to the idle command
-    Bit 3: HiAlertIRq - Set when the Status1 register HiAlert bit is set
-    Bit 2: LoAlertIRq - Set when the Status1 register LoAlert bit is set
-    Bit 1: ErrIRq - Set when any bit in ErrorReg gets set
-    Bit 0: TimerIRq - Set when the TCounterValReg decrements to zero
-
-Writing 0x14 to the "DivIEnReg" has the following meaning:
-
-    Bit 7: IRQPushPull=0 - IRQ is an open-drain output pin
-    Bit 6: reserved=0 - no known effect
-    Bit 5: reserved=0 - effect unknown
-    Bit 4: MfinActEn=1 - Allow the MFIN active interrupt request to trigger IRQ
-    Bit 3: reserved=0 - boundedly undefined
-    Bit 2: CRCIEn=1 - Permit the "DivIrqReg" bit CRCIRq to trigger IRQ
-    Bit 1: reserved=0 - do not set to 1 on pain of nothing
-    Bit 0: reserved=0 - has no purpose other than to confuse
-
-The register "DivIrqReg" corresponds to "DivIrqEn", and has the following bit definitions:
-
-    Bit 7: Set2 - when written as 1, a bit value of 1 in bits 6-0 of the byte written set the corresponding register bit; when written as 0, bits 6-0 clear the corresponding register bit
-    Bit 6: reserved - don't ask
-    Bit 5: reserved - don't tell
-    Bit 4: MfinActIRq - MFIN is active
-    Bit 3: reserved - just leave it at zero and back away slowly
-    Bit 2: CRCIRq - when 1, the CalcCRC command is active and all data is processed
-    Bit 1: reserved - nothing to see here
-    Bit 0: reserved - are you feeling lucky, punk?

 Interrupt method was not working because it seems reading a card does not trigger one.
