15.8 Interrupt transfer registers
15.8.1 HcINTLBufferSize register (R/W: 33H/B3H)
This register allows you to allocate the size of the INTL buffer to be used for interrupt
transactions. The default value of the buffer size is set to 128 bytes, and the
maximum allowable allocated size is 4096 bytes. Table 85 shows the bit description
of the register.

15.8.2 HcINTLBufferPort register (R/W: 43H/C3H)
In addition to the HcDirectAddressData register, the ISP1362 provides this register to
act as another data port for accessing the INTL buffer. The starting address for
accessing the buffer is always fixed at 0000H. Therefore, random access of the INTL
buffer is not allowed. The bit description of the HcINTLBufferPort register is given in
Table 86.
