Section 6 HCS12 Core Block Description
6.1 CPU12 Block Description
Consult the CPU12 Reference Manual for information on the CPU.
6.1.1 Device-specific information
When the CPU12 Reference Manual refers to cycles this is equivalent to Bus Clock periods. So 1 cycle is
equivalent to 1 Bus Clock period.
6.2 HCS12 Module Mapping Control (MMC) Block Description
Consult the MMC Block Guide for information on the HCS12 Module Mapping Control module.
6.2.1 Device-specific information
INITEE
Reset state: $01
Bits EE11-EE15 are "Write once in Normal and Emulation modes and write anytime in Special
modes".
PPAGE
Reset state: $00
Register is "Write anytime in all modes"
For Memory Size Registers see Table 1-4.
6.3 HCS12 Multiplexed External Bus Interface (MEBI) Block
Description
Consult the MEBI Block Guide for information on HCS12 Multiplexed External Bus Interface module.
6.3.1 Device-specific information
PUCR
Reset state: $90
6.4 HCS12 Interrupt (INT) Block Description
Consult the INT Block Guide for information on the HCS12 Interrupt module.
