S12XECRG Interrupt Enable Register (CRGINT)

This register enables S12XECRG interrupt requests.

Table 7-4. CRGFLG Field Descriptions

Field

Description

7

RTIF

Real Time Interrupt Flag — RTIF is set to 1 at the end of the RTI period. This flag can only be cleared by writing
a 1. Writing a 0 has no effect. If enabled (RTIE=1), RTIF causes an interrupt request.
0 RTI time-out has not yet occurred.
1 RTI time-out has occurred.

6

PORF

Power on Reset Flag

—

PORF is set to 1 when a power on reset occurs. This flag can only be cleared by writing

a 1. Writing a 0 has no effect.
0 Power on reset has not occurred.
1 Power on reset has occurred.

5

LVRF

Low Voltage Reset Flag

—

LVRF is set to 1 when a low voltage reset occurs. This flag can only be cleared by

writing a 1. Writing a 0 has no effect.
0 Low voltage reset has not occurred.
1 Low voltage reset has occurred.

4

LOCKIF

IPLL Lock Interrupt Flag

—

LOCKIF is set to 1 when LOCK status bit changes. This flag can only be cleared

by writing a 1. Writing a 0 has no effect.If enabled (LOCKIE=1), LOCKIF causes an interrupt request.
0 No change in LOCK bit.
1 LOCK bit has changed.

3

LOCK

Lock Status Bit

—

LOCK reflects the current state of IPLL lock condition. This bit is cleared in Self Clock Mode.

Writes have no effect.
0 VCOCLK is not within the desired tolerance of the target frequency.
1 VCOCLK is within the desired tolerance of the target frequency.

2

ILAF

Illegal Address Reset Flag

—

ILAF is set to 1 when an illegal address reset occurs. Refer to S12XMMC Block

Guide for details. This flag can only be cleared by writing a 1. Writing a 0 has no effect.
0 Illegal address reset has not occurred.
1 Illegal address reset has occurred.

1

SCMIF

Self Clock Mode Interrupt Flag — SCMIF is set to 1 when SCM status bit changes. This flag can only be
cleared by writing a 1. Writing a 0 has no effect. If enabled (SCMIE=1), SCMIF causes an interrupt request.
0 No change in SCM bit.
1 SCM bit has changed.

0

SCM

Self Clock Mode Status Bit — SCM reflects the current clocking mode. Writes have no effect.
0 MCU is operating normally with OSCCLK available.
1 MCU is operating in Self Clock Mode with OSCCLK in an unknown state. All clocks are derived from PLLCLK

running at its minimum frequency f
