XTAL1, XTAL2
(Crystal oscillator
input)
Crystal inputs for the internal oscillator.
All port pins are configured as inputs (high impedance) during RESET, except for Port 1 and Port 0. Port
1 is configured as a multiplexed address/ data bus. Port 0 pins P00-P04 are configured as address out. And
pins P05-P07 are configured as inputs.
Registers
The IA88C00 supports a 256-byte register address space. Addresses 00H-BFH contain two sets of
registers. Set one contains control registers that are only accessible by register direct commands. Set two
contains data registers that are only available via register indirect, indexed, stack and DMA commands,
Note that address space E0H to FFH in Set one is further divided into two banks. The state of bank select
bit in the Flag register determines which bank is accessed.
The register space is shown in Figure 7.
