23.6.10 TSC I/O group x counter register (TSC_IOGxCR) (x = 1..8)
Address offset: 0x30 + 0x04 x Analog I/O group number
Reset value: 0x0000 0000
23.6.11 TSC register map
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.
0: Acquisition on analog I/O group x is ongoing or not started
1: Acquisition on analog I/O group x is complete
Note: When a max count error is detected the remaining GxS bits of the enabled analog I/O
groups are not set.
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.
0: Acquisition on analog I/O group x disabled
1: Acquisition on analog I/O group x enabled

Bits 31:14 Reserved, must be kept at reset value.
Bits 13:0 CNT[13:0]: Counter value
These bits represent the number of charge transfer cycles generated on the analog I/O group
x to complete its acquisition (voltage across C
S
has reached the threshold).
