AC Specifications
The AC characteristics of the IA82527 are provided in the figures and tables of this chapter.
The IA82527 can be configured to operate in the following parallel and serial CPU interface
modes:
• Mode 0: 8-Bit Multiplexed Intel Architecture
• Mode 1: 16-Bit Multiplexed Intel Architecture
• Mode 2: 8-Bit Multiplexed Non-Intel Architecture
• Mode 3: 8-Bit Non-Multiplexed Non-Intel Architecture
• Serial Interface Mode
The AC characteristics of these modes in operation are provided as follows:
• Mode 0 and Mode 1: General Bus Timing (Tables 10 and 11/Figure 7)
• Mode 0 and Mode 1: Ready Timing for Read Cycle (Table 10 and 11/Figure 8)
• Mode 0 and Mode 1: Ready Timing for Write Cycle with No Write Pending (Table 10
and 11/Figure 9)
• Mode 0 and Mode 1: Ready Timing for Write Cycle with Write Pending (Table 10 and
11/Figure 10)
• Mode 2: General Bus Timing (Table 12 and 13/Figure 11)
• Mode 3: Asynchronous Operation, Read Cycle (Table 14 and 15/Figure 12)
• Mode 3: Asynchronous Operation, Write Cycle (Table 14 and 15/Figure 13)
• Mode 3: Synchronous Operation, Read Cycle (Table 16 and 17/Figure 14)
• Mode 3: Synchronous Operation, Write Cycle (Table 16 and 17/Figure 15)
• Serial Interface Mode: icp = 0 and cp = 0 (Table 18 and 19/Figure 16)
• Serial Interface Mode: icp = 1 and cp = 1 (Table 18 and 19/Figure 17)
