MPC2F35E2 MEGAWIN [Megawin Technology Co., Ltd], MPC2F35E2 Datasheet - Page 11

• Manufacturer Part Number: MPC2F35E2
• Description: Low-speed USB micro-controller
• Manufacturer: MEGAWIN [Megawin Technology Co., Ltd]

At the 6M Hz external crystal, the internal clock source of MPC2F35 is 3M Hz by the default value.
Release halt mode enable flag
Programmer can select the interrupt sources to release the halt mode through this register.
0: Disable (default), 1: Enable
After setting RLH_EN register, once there is one interrupt to release the halt mode, the programmer can
check the corresponding bit of the IRQ_ST register to know which interrupt source to execute this
release process.
Timer
Timer 0
When timer 0 is used, it starts to pre-load value to this down-counter by setting the STC bit in the
TM0_CTL SFR and its underflow frequency (F
