When TSMODE = 2, each trigger event adds 4 half-words to the buffer (assuming TSAV=0), first
half-word being XPOS of ADC_XPOSR register followed by YPOS of ADC_YPOSR register and
finally Z1 followed by Z2, both located in ADC_PRESSR register.
When TAG is set (ADC_EMR), the CHNB field (4 most significant bit of the ADC_LCDR) register
is set to 0 when XPOS is transmitted and set to 1 when YPOS is transmitted, allowing an easier
post-processing of the buffer or better checking buffer integrity. In case 4-wire with pressure
mode is selected, Z1 value is transmitted to the buffer along with tag set to 2 and Z2 is tagged
with value 3.
XSCALE and YSCALE (calibration values) are not transmitted to the buffer because they are
supposed to be constant and moreover only measured at the very first start up of the controller
or upon user request.
There is no change in buffer structure whatever the value of PENDET bit configuration in
ADC_TSMR register but it is recommended to use the pen detection function for buffer post-pro-
cessing (refer to
“Pen Detection Status” on page
932).
