Event Manager (EV) Functional Blocks
6-6
- Software writing a 1 to the interrupt flag, which has been identified by the
interrupt vector ID, is required to clear the flag. Reading the interrupt vec-
tor ID no longer automatically clears the associated flag.
- PDPINTA/B is now enabled following reset.
- Only one write is required to initialize COMCONA/B, not two as on the
’C240.
6.1.2 EV Pins
Each EV module has eight device pins available for compare/PWM outputs:
- Two GP timer compare/PWM output pins:
EVA EVB
T1CMP/T1PWM T3CMP/T3PWM
T2CMP/T2PWM T4CMP/T4PWM
- Six (full) compare/PWM output pins:
EVA EVB
PWM1 PWM7
PWM2 PWM8
PWM3 PWM9
PWM4 PWM10
PWM5 PWM11
PWM6
PWM12
The EVA module uses three device pins, CAP1/QEP1, CAP2/QEP2, and
CAP3, as capture or quadrature encoder pulse inputs.
The EVB module uses three device pins, CAP4/QEP3, CAP5/QEP4, and
CAP6, as capture or quadrature encoder pulse inputs.
The timers in the EV module can be programmed to operate based on an ex-
ternal clock or the internal device clock. The device pin TCLKINA/B supplies
the external clock input.
The device pin TDIRA/B is used to specify the counting direction when a GP
timer is in directional up-/down-counting mode.
The device pins are summarized in Table 6–1 and Table 6–2.
