Reading out counter data
The counter data is read out via a PTDx data buffer. The counter data can be read out at any time.
Timer 0 data: PTD0[7:0] (D[7:0]) / 8-bit timer 0 counter data register (0x40162)
Timer 1 data: PTD1[7:0] (D[7:0]) / 8-bit timer 1 counter data register (0x40166)
Timer 2 data: PTD2[7:0] (D[7:0]) / 8-bit timer 2 counter data register (0x4016A)
Timer 3 data: PTD3[7:0] (D[7:0]) / 8-bit timer 3 counter data register (0x4016E)
Timer 4 data: PTD4[7:0] (D[7:0]) / 8-bit timer 4 counter data register (0x40176)
Timer 5 data: PTD5[7:0] (D[7:0]) / 8-bit timer 5 counter data register (0x4017A)
