register for future read and write operations, as well as issues
special function commands.

Description
CMD
7 Select Command Register. Must write as 1 when addressing COMMAND register.
TYPE
6:5 Selects type of transaction to follow in subsequent data transfers:
FIELD VALUE
DESCRIPTION
00
Repeated byte protocol transaction
01
Auto-increment protocol transaction
10
Reserved — Do not use
11
Special function — See description below
Transaction type 00 will repeatedly read the same register with each data access.
Transaction type 01 will provide an auto-increment function to read successive register
bytes.
ADDR/SF 4:0 Address field/special function field. Depending on the transaction type, see above, this
field either specifies a special function command or selects the specific
control-status-data register for subsequent read and write transactions. The field values
listed below apply only to special function commands:
FIELD VALUE
DESCRIPTION
00100
Interrupt set — forces an interrupt
00101
Proximity interrupt clear
other
Reserved — Do not write
The interrupt set special function command sets the interrupt bits in the status register
(0x13). For the interrupt to be visible on the INT pin, the proximity interrupt enable bit
(PIEN) in the enable register (0x00) must be asserted.
The interrupt set special function must be cleared with an interrupt clear special function.
The proximity interrupt clear special function clears any pending interrupt and is self
clearing.
