Auto-increment/non auto-increment address

The STMPE812 supports auto-increment accesses on all, except for TSC data register

(0x44). While accessing auto-increment register location, consecutive read/write access

data from the consecutive registers. Note that for register accesses started on auto-

incremental addresses, the address 0x44 is skipped.

For example:

Write register address (0x40)

Read data (data of 0x40)

Read data (data of 0x41)

Read data (data of 0x42)

Read data (data of 0x43)

Read data (data of 0x45) <= 0x44 is skipped.

0x44

TSC_DATA

Non auto-increment address

Registers from 0x50 - 0x5F are accessible only if “PWM_OFF” bit in SYS_CTRL is set to “0”.
