The SIEL is a 32-bit read/write register. Each pair of bits corresponds to an external interrupt request. The
EDx bit, if set, specifies that a falling edge in the corresponding IRQ line will be detected as an interrupt
request. When the EDx bit is 0, a low logical level in the IRQ line will be detected as an interrupt request.
The WMx (wake-up mask) bit, if set, indicates that an interrupt request detection in the corresponding line
causes the MPC561/MPC563 to exit low-power mode.
6.2.2.2.8
The SIVEC is a 32-bit read-only register that contains an 8-bit code representing the unmasked interrupt
source of the highest priority level. The SIVEC can be read as either a byte, half word, or word. When read
as a byte, a branch table can be used in which each entry contains one instruction (branch). When read as
a half-word, each entry can contain a full routine of up to 256 instructions. The interrupt code is defined
such that its two least significant bits are 0, thus allowing indexing into the table. The two possible ways
of the code usage are shown on
