32.12.2.2 eMIOS Global FLAG Register (GFLAG)

The GFLAG is a read-only register that groups the FLAG bits from all channels. This organization

improves interrupt handling on simpler devices. These bits are mirrors of the FLAG bits of each channel

GPREN

Global Prescaler Enable bit. The GPREN bit enables the prescaler counter.

0 Prescaler disabled (no clock) and prescaler counter is cleared

1 Prescaler enabled

25–16

Reserved, should be cleared.

15–8

GPRE[7:0

Global Prescaler bits. The GPRE[7:0] bits select the clock divider value for the global prescaler, as shown in

Table 32-7.

7–0

Reserved, should be cleared.
