22.3: Handshaking Error Indication and Mask Registers (HShake1)
The local handshaking error indication register indicates pending handshaking error requests from the
GPPINT chiplets.

0 = Normal operation of the corresponding chiplet.
1 = The corresponding chiplet did not deassert its DTACK signal.
Exception: The signals TOError and IntError (HShake2(1-0)) have the following meaning: Normal opera-
tion GPP deasserts Strobes without waiting for DTACK assertion Watchdog Timeout in REST state
Watchdog Timeout in REQ state. An active bit of the handshaking error indication register is reset by
removing the cause for the malfunctioning of the chiplet and by writing a one into the corresponding bit
position. Reading one register will reset all bits of this register if the "clear-register" option is set in
ConfGP1(2). The handshaking error indication mask register bits control the propagation of the GPPINT
handshaking error requestof the register HShake1. HSMask1 controls propagation to the signal FElocHS
(bit 0 of IRQGP1 register). The mask registers allow read and write access.
0 = The corresponding handshaking error indication bit is masked (DEFAULT).
1 = The corresponding request bit is active (for HSMask1, the corresponding request bit activates signal
FElocHS (bit 0 of IRQGP1 register). "Clear-register" option set in ConfGP1(2).
