Tsc I/O Group X Counter Register (Tsc_Iogxcr) (X = 1 - STMicroelectronics RM0365 Reference Manual

Touch sensing controller (TSC)
Bits 31:24 Reserved, must be kept at reset value.
Bits 23:16 GxS: Analog I/O group x status
These bits are set by hardware when the acquisition on the corresponding enabled analog I/O
group x is complete. They are cleared by hardware when a new acquisition is started.
Note: When a max count error is detected the remaining GxS bits of the enabled analog I/O
Bits 15:8 Reserved, must be kept at reset value.
Bits 7:0 GxE: Analog I/O group x enable
These bits are set and cleared by software to enable/disable the acquisition (counter is
counting) on the corresponding analog I/O group x.
