USER’S MANUAL
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU.
Kill Reservation – In case of a bus cycle initiated by a STWCX instruction issued by
the CPU core to a non-local bus on which the storage reservation has been lost, this
signal is used by the non-local bus interface to back-off the cycle.
Retry – Indicates to a master that the cycle is terminated but should be repeated. As
an input, it is driven by the external slave to retry a cycle.
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Pin Name: irq4_b_at2_sgpioc4
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU.
Address Type – A bit from the address type bus which indicates one of the 16 “ad-
dress types” to which the address applies. The address type signals are valid at the
rising edge of the clock in which the special transfer start (STS) is asserted. AT[2] iden-
tifies an access as either data or instrucion.
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Pin Name: irq5_b_sgpioc5_modck1
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU.
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Mode Clock [1] – Sampled at the negation of PORESET in order to configure the
phase-locked loop (PLL)/clock mode of operation.
Pin Name: irq6_b_modck2 - irq7_b_modck3 (2 pins)
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU.
Mode Clock [2:3] – Sampled at the negation of PORESET in order to configure the
PLL/clock mode of operation.
Pin Name: tsiz0 - tsiz1 (2 pins)
