Offset:
• RC[15:0]: Register C Value
When the counter reaches this value, seven events can occur:
6048B–ATARM–29-Jun-06
– The CPCS flag is set in the status register.
– If enabled, CPCS interrupt is generated.
– If bit CPCTRG (bit [14] of the GPTX_MR) is high, the counter is reset and restarts at 0x0000 at the next valid
– The counter clock can be disabled according to CPCDIS (bit [7] of the mode register).
– The counter can be stopped according to CPCSTOP (bit [6] of the mode register).
– TIOAx pin can be set, clear, toggle or unchanged following bits ACPC[1:0] of the mode register.
– TIOBx pin can be set, clear, toggle or unchanged following bits BCPC[1:0] of the mode register.
