The GPTMCR contains parameters for configuring the GPT.
The IARB field is used to arbitrate between simultaneous interrupt requests of the same priority. Each
module that can generate interrupt requests must be assigned a unique, non-zero IARB field value. Re-
fer to 3.8 Interrupts for more information.
This address is currently unused and returns zeros if read. It is reserved for GPT factory test.
Specifies which GPT interrupt source is given highest internal priority
Specifies the priority level of interrupts generated by the GPT.
Most significant nibble of interrupt vector number generated by the GPT when an interrupt service re-
quest is acknowledged.
0 = Internal clocks not shut down
1 = Internal clocks shut down
0 = Ignore FREEZE
1 = FREEZE the current state of the GPT
0 = Normal operation
1 = Stop prescaler and pulse accumulator from incrementing. Ignore changes to input pins.
0 = Has no meaning
1 = If STOPP is asserted, increment prescaler once and clock input synchronizers once.
0 = Registers with access controlled by SUPV bit are accessible from either user or supervisor priv-
1 = Registers with access controlled by SUPV bit are restricted to supervisor access only.
